Dogs and responsibilities and consequences

I’ve been thinking about dogs today. About their owners/keepers. About my Dad.

I think the guy with the dog that ran into my fellow hiker, and who then was reluctant-at-best to leash the dog after she got injured is now removed from the hiking group. I think that’s just. He didn’t come back to help us carry her down. While I’m not a fan of leaving dogs in cars in Texas in the summertime, we aren’t in Texas. It was a cold day; carrying a person down the trail is a hard job even for a sizeable group of people, and the dog could have been left in the car.

That makes me think of my father and the dogs in his life. He had a lady friend with a Boston terrier. I think he liked her better than the dog, but maybe it was a toss up. The Boston had a rough childhood with older dogs that beat up on him, and his attitude toward the rest of the canine world was, “it’s me or you, and I’m getting my licks in first.” He’d attack any other dog without provocation.

Dad would still let him off leash. I know Dad paid several ~$500 vet bills because of “accidents”. He still couldn’t bear to keep the Boston on a leash.

Later, he had another friend with another two dogs, and Dad loved these dogs too, taking them for walks, and again, he couldn’t bear to keep them on a leash. Until one day one of them ran out into traffic, was hit by a car and killed. Dad was sorry, but sorry in the sense of saying so, not in the sense of doing something about it.

I loved my Dad, don’t get me wrong, but I didn’t always respect my Dad or like my Dad. To this day, thinking about this makes me feel sick in my stomach. And sad, deeply sad, because I just don’t understand it.

Sad, too, because I realize that one of his legacies is that I have never had a man in my life who has had my back. When the going got tough, I took care of it. I took care of us. Or I took care of me. I shut up and dealt. I didn’t like it, but after all, in my world growing up, men are never responsible for anything. They may be “sorry”, but they aren’t sorry. If I don’t toe the line, if I complain, if I insist then I nag, and I become a harridan like my mother. Since that’s the last thing in the world I want to do, I put up with a hell of a lot of shit.

A hell of a lot of shit.

I wonder if there were good men in my life, and I didn’t recognize them at the time. Or if I picked the best of what I had available to me (after college, never exactly a glut of suitors).

I wonder if I’ll ever find someone again. If I do if I’ll find myself again putting up with a hell of a lot of shit. Whether I will tell it to take a hike. Whether I have finally changed enough that if I let him in my life, that it will be better. If I will ever again find anyone at all.

I try not to focus on loneliness. On feeling unloved. None of that gets you anywhere but a pity party. Focus on the love you want to give, not the love you want to get. It works better that way. But days, some days, today, all of this tastes like ashes, and I want what I wanted, what I still want, and I know I will never get it, and I will have to make do.

And tomorrow I will wake up and make do better than anyone has ever made do before. But tonight, tonight, I am sad for all that was, and for all that is, and for all that will not be.


Before I left Spokane, my friend said to me that he hadn’t realized how much of his identity was tied up with his wife. When she passed away, and as he’s dealt with his grief, he’s had to examine his concept of who he is and what he wants. This is no easy task.

I don’t know that I said much in reply aside from offering sympathy. I won’t claim to be an expert at this one, nor have I had a major grief, like his, to deal with.

Every time I’ve had a relationship end (my, I’ve had a lot more of these than I ever wanted to), I have had to adjust my sense of self. It is easier because I’ve spent a lot of time alone — then I know who I am when no one else is around, and I am mostly returning to this after a relationship ends.

What’s been harder for me is letting go of the things I wanted to be, but will never become. The one that hurts the most is that I will never be a parent. If I can’t find the husband, it makes it hard to have the child. I was never willing to go at that solo. Eventually, I got too old. 45 is pretty definitive. There are days when 45 is pretty hard to take.

There’s all the self-questioning that I can’t quite stop. I should have gone further into online dating. Sooner. Many boyfriends I should have broken up with sooner. I should have dropped the hard shell of defensiveness from my childhood sooner, and softened up. I should have been wiser about people, as if I could have just had the realization that when other people treated me poorly that this is not a reflection on my worth sooner.

We can regret, but we cannot change the past. We can only go on from here.

When we depart from the standard story, or any story we’ve told ourselves for a long time, it takes adjustment. I’m still trying to figure out who I am, as a 45 year old woman, aging more quickly than I’d like, without a family, without a significant other, with an anxiety problem that is fortunately not troubling me much at the moment, and, right now, in a new place without any friends or close friends to lean on.

We need more stories for women. More for men too, but I know less about that. I have female friends who are childless and happy with that, but I can’t think of many stories where that is the outcome for women. It never was an option in any of my happily ever afters. So I have no view of what this should be, even looking at my friends and trying to see through their eyes.

The only thing I’ve figured out is that you have to concentrate on the love you can give, not on the love you wished to receive. That is the path to happiness, but it is not easy to travel it.

One thing I hope is that I find honor and integrity, grace, generosity and kindness, warmth and caring, and lots of love freely given to others in who I am, whoever that may be.

When is enough enough?

I had a phone call with our Chief Diversity Officer, and I went and had a visit with the Dean of Faculties today about why I am leaving my current university.

I feel an obligation to do this and do this well. I know nothing is going to happen because of what I say. I just hope to make it easier for the next person. But dredging up all that stuff makes me sad. I never feel like I say the right things. It was a hard day.

This evening ended with a visit to my book club. One member is in human resources, and told me that the university will never change unless I file a complaint with the EEOC or another external enforcing agency. And I can see her point and logic, but forgive me if tonight this was just too much. I’m doing my best here to try to do right by everybody, to speak my truth, to tell the right people. And this is still not enough?

Truth is I think she’s right. Truth is I’m not enthused about what is asked of me. Truth is I worry about repercussions hurting me, even though I’m soon to be gone.

Maybe that’s all just excuses for not wanting to delve into things that bother me and make me sad again.

A friend tried to remind me of all the things that have gone right lately. But I’m not in the mood for that. Tonight I give myself permission to be sad. Tomorrow is another day, with a new set of challenges. I will have to buck up for them. Tomorrow, with renewed strength, I can think about this again.

Meanwhile I am sad that I am leaving. Sad that there wasn’t a better outcome here. Sad that I didn’t have the right words to say, the magic words, to make things right. Sad to leave my home and my friends behind.

If that seems ungrateful for all the good things that I have had happen, tonight, so be it. I am truly grateful for the good things. But I am also very very sad about a lot of things too.

Being Different from Everyone Else

Last post, I mentioned my atheism. This is something that sets me apart from the vast majority of my friends and colleagues. It makes people uncomfortable. This is no surprise; when religion teaches that unbelievers are evil and horribly mistaken, where religion gives comfort to those in pain, when many believers disbelieve for a time because they are angry with God, what is a believer to think of another who rejects the faith?

When I was 10 or 11 years old I had a friend ask me why it was I believed in God. I had never considered this a question before. I think many people never consider the question unless they are angry and in pain — i.e. mad at God for some circumstance. For me it was just a completely new thought, an entirely reasonable thought, and I spent a long time with it. I have spent the last 34-35 years thinking on this on and off. When I was younger, I asked this of the adults around me, and I certainly didn’t get a satisfactory answer. I asked my parents, the preachers and teachers in the church, and I didn’t get a satisfactory answer. I read the bible, and I didn’t find that convincing either.

For a while, as a distressed teenager from a troubled home, I tried to follow the prescription of religious friends. To ask for faith and faith would be given to me. I asked, I prayed, I read the Bible some more, but the harder I tried, the more I learned, the more doubt filled my mind. Faith was not given to me. Again, I turned my critical faculties on the question of the existence of God, any God.

The arguments for atheism made a lot more sense. And let me say to those who are reading this who believe. I believe in exactly one fewer god than you do. Why don’t you believe in the Greek gods, or the Roman gods, or the Hindu gods or any of the rest? What makes the one you believe in special is usually that you were raised in that church or are surrounded by that culture. Think of all the gods you have rejected, and remember, I have rejected just one more.

Some say we need God to explain the existence of the universe, but I’d reply by asking why don’t we then need something to explain the existence of God? I stop one step earlier in the process that these believers do. The argument about intelligent design also did not do much for me; yes, there is much about the world that is complicated and elegant, but to claim that this must be created an intelligent designer is to fail to understand fully the theory of evolution and the power of small changes over long periods of time. There are other arguments. I will spare you even a short review of them. I am sure you can go find more information if you are curious.

Another thing. We certainly don’t see any God influencing our day to day life — though some people like to claim they’ve seen it or seen miracles — I believe that people are often experts at fooling themselves and seeing what they want to see. Even me, and I try to be diligent on this issue.

I’ve been in the minority for most of my life with this lack of belief; having other people disagree with me on this point is hardly upsetting. I don’t always like what others say — when people claim it takes faith to be an atheist, that just gets my dander up. The burden of proof is on the person asserting the positive. I am not asserting a positive. When people wonder whether I have a moral code, I have to often bite my tongue in the course of employing it.

I wonder how people can believe what some of the crazy things that the Bible and churches teach, yet be otherwise rational human beings. I am sure they think the exact same of me! One thing being in the minority teaches you is just how rude it would be to express that thought aloud. And unproductive. People that I do respect believe these things. They have reasons I do not understand. It is not my job to convince them, it is my job to live my life authentically and to celebrate when I see others do the same, even if their way is different from mine.

My favorite character from literature, my heart’s favorite at least, is Cordelia Naismith Vorkosigan from Lois McMaster Bujold’s works Shards of Honor and Barrayar, collected in the single volume Cordelia’s Honor. While a religious person might ask “what would Jesus do?” my question is “what would Cordelia do?” Cordelia is definitely a theist. I am definitely not. Sometimes my respect and love and admiration for this fictional character is what reminds me that we are all different, and what helps me see, just a little bit, of the perspective from the other side.

It is never easy to go against the flow. My integrity demands this of me. You may not agree; you may want to argue. Please keep in mind that I have, indeed heard it all before. More than once. I hope you can try to respect that, as I also try to respect your beliefs. We won’t always succeed, but at least we can be civilized about our disagreement.

Must be making progress

I must be making progress.

The job offer negotiation is on, and it started off from a reasonable position.

I feared getting a low offer for less money than I am making now. I know I would have dealt with that if it had come, but I also know that my spirits would have taken a hit if that had happened. Last year’s incident was more than enough of that for one life-time.

Good news. The offer is for more than I’m making now or would be next year, but not overly generous. I know where I want to be on this negotiation so I said, “I’d like to open at this higher amount.” I got some hemming and hawing and referred to talk to someone else, but it wasn’t a “no way,” and it was respectful. They have some reasons. I have some reasons. All I want to do is meet at a good spot in the middle. I think — I hope — we’ve got a good chance of making that happen.

Money can’t buy happiness, but it can make you awfully comfortable while you’re being miserable — Clare Boothe Luce

Meanwhile the sort-of-kind-of good cop/bad cop routine (in which both players at the school — dean and department chair — are playing both roles) amused me.

I have some more questions to ask about this whole deal. But that’s how this works. You ask questions, you get answers, you ask more. You negotiate. You revisit and refine for a little while.

And one more small victory.

I had a student come by today to do some linear algebra. Over spring break! This is one I sought to put the fear of god into last week on Thursday, and apparently I succeeded. A low score was obtained on an exam. A high score was obtained on a homework. Dr. Jinx wonders how this happened and called a bunch of students in to demonstrate that they do, in fact, know how to do a homework problem. Several succeeded. This one did not. Bad juju. I gave him a zero on the homework problem, and the lecture about how if you put the time into understanding the material, the exam scores would follow right along with it.

I don’t like being the bad cop, but I’m betting that at the end of the semester, having come to terms with this material, this young man is going to be happier with himself than if he scraped by or had to drop out. There is something immensely satisfying about conquering a demon that’s scaring you. I think he can do it. We worked on linear independence and linearly independent functions. He knew more when he left than when he arrived. Success.

I hope I can do what I need to do too. I can walk around the world one step at a time. Watch me.

Fear and Flashbacks and Moving Forward

Eleanor Roosevelt says that you should

Do one thing every day that scares you.

I don’t know how I’m doing on the one-a-day count, but I know that in this past academic year, I’ve addressed a lot of things that have terrified me.

  • Going on the job market.
  • Deciding to go after tenure-track positions, which required me to write a research statement. I didn’t think I could. I was afraid to try. But I did it.
  • The interviews themselves have scared me on and off. Sometimes more confident, sometimes more shaky.
  • Dealing with my home department and its problems. There are people in that department whose lack of anger management and general fairness creates a hostile and intimidating environment.
  • Having to raise issues outside the department and within, to face these problems.
  • Dealing with people who are acting in an obstructionist manner.
  • Needing to go back to authorities within the university about even more blatant diversity and climate issues.

And I have gotten through most of that, though some is still pending. With a ton of discouragement, and not a lot of confidence. I have kept moving forward, nevertheless.

But tomorrow … tomorrow we open a job negotiation. I remind myself that we should be on the same side. But last spring’s fiasco has left me with anything but confidence on that point.

I am dealing with things that I am not sure are major enough to be called flashbacks, but they are like flashbacks. I am suddenly back in that emotional space where nothing I can do or say will change anything, I am not being supported by the person closest to me, and I am scared and paralyzed. I feel the obligation to say the right thing to make things go right, but I know that you cannot make unreasonable people reasonable. That is beyond my super-powers.

What if this happens again? I don’t want to stay where I am. I will not go somewhere that isn’t treating me right. What if we end up in the grey zone of uncertainty? Then how do I deal? What if I say the wrong thing or don’t deal with things perfectly?

And that’s ridiculous. I don’t have to be perfect. Neither does that dean have to be perfect. We both just have to be good enough. We both just have to want to make a deal that is good for the school and good for me, then work on what exactly that is.

Well, at least this time, I cannot lose a significant other over what happens. Right?

A principles/ideas of the negotiation:

We all want me to accept this job offer, and bring what I have to the school. This negotiation is about making that happen.

Tools that can be used:

  1. Figure out our common goals and priorities.
  2. Ask why the other person has whatever stance they have.
  3. Generate alternative ideas that might help with the problem. This can involve hiring me with a different title, for example.
  4. How can funds get best used to further everyone’s goals?
  5. Find out from others some details on start-up packages.
  6. I don’t have to respond to anything immediately. “I need some time to think about that.”
  7. If offered a salary that is obviously too low, the pregnant pause and, “That was lower than I was expecting/Is less than I am making now.”
  8. Find somewhere that we can have success together.

That’s the basics of what I can do. On the rest I have to trust.

A friend reminded,

Fear is a sign of profound opportunity.

And that goes along with a corollary,

Make the most of the opportunity in front of you.

The March Forward

Wednesday I have two meetings. One with my REU PI and one with my department chair, both addressing problems I’ve been having with regards to my job responsibilities. I seem to not understand what they are? If someone as conscientious and as careful as I am is this confused, that is a sign of severe departmental mismanagement.

The path is integrity. Face problems head on. Listen. Listen. Listen. Listen to what others say. But brook no nonsense. There are things that are not okay. Know my boundaries and limits, and know what I hope to achieve.

I am going to plan for a high anxiety morning. I will have my medication on hand. I will take it the night before to get to sleep if I need it. I will meditate. I will breathe in and out, pausing slightly between exhale and inhale to feel the moment of nothingness.

What is it I tell my students? Believe in yourself. Bring integrity to your work. Have honor. That’s all I need to do here. Believe. Have integrity. Have honor.

I know that no matter what I do, it may not (probably will not) fix anything. But at least by following this path, I will have done what I could.

A friend posted this to Facebook this morning:

“Civil disobedience is not our problem. Our problem is civil obedience. Our problem is that people all over the world have obeyed the dictates of leaders…and millions have been killed because of this obedience…Our problem is that people are obedient allover the world in the face of poverty and starvation and stupidity, and war, and cruelty. Our problem is that people are obedient while the jails are full of petty thieves… (and) the grand thieves are running the country. That’s our problem.” — Howard Zinn

I hope that by bringing this problem to the attention of those with oversight responsibilities at the university, if change will not happen from within the department, it will be encouraged from without. There are good people who care about doing things right. Maybe not enough of them. But they are there, and some of them are in the positions of authority that they should be in.

I will not be a good, obedient girl. I will question authority. I will do so politely, professionally, respectfully, and forcefully. Fearfully too, but hopefully the only people who will know that are the ones who would offer me support, strength and love.

On Being Angry

For the past few days, I have been angry. I have been wronged. I have been afraid. I have been treated unjustly. And so, I have been angry.

Here’s the thing. I don’t like being angry. I don’t like myself when I am angry. I don’t want to continue to be angry. At the same time, that I am angry means there are problems to be solved, and things to be fixed. My anger helps me to do that.

Can I find a better way?

What would a better way be?

Is there a path to peace with those who wrong you? With those who do wrong knowingly?

What if I was the teacher, and these were my students doing wrong? How would that change things?

I get angry with students, frustrated, tired. But one thing that’s different when I am dealing with students: in these young people, almost without exception, no matter how bad the behavior may be, I am always trying to see through to the possibility that they can do right and grow into honorable, kind, productive human beings. In my interactions with them, I want them to see themselves as those honorable, kind, productive human beings. Or, with the possibility of becoming those honorable, kind, productive human beings. Whatever bad behavior I am called upon to address: it is their behavior; it is not their identity. I want to leave them with that image of themselves as greater, rather than lesser. I open up my heart as wide as I can so that they can see themselves as I can see them, full of promise, hope, possibility, honor.

You may have made a mess. But you are not a mess. You have all the potential that you need to be someone worthy and worthwhile. You get to decide what you do next and how you handle this. Choose well.

Can I do this with a 60 year old department chair too? Can I even try to see this from where he’s at? There is the world he knows well, the world he’s lived in, and the things he’s been taught because of his position. There is a major assumption of privilege. An ignorance of the day-to-day lives of those who report to him. Ignorance of the careers of those who require his good judgment and wisdom in handling our concerns. Perhaps he knows nothing of this. Never considered it to be important. Never saw the people in front of him as human beings, with ambitions and motivation just like him.

Is there the possibility of growth, honor, better in the future?

Of course there is a possibility for growth, honor, and better in the future. There may have been too much bad for me to want to remain for the long term. But can I uphold honor while advocating for fairness, can I be peaceful when addressing wrongs? Can I be courageous in facing those with more power than I have and, armed with little besides my integrity, be a force for good?

That is the standard I set for myself. To let go of the anger. To arm myself with integrity. To see the good and to help others see it. To allow myself to walk away where there is nothing to be gained or when too much has been lost, but to open the doors wide to change for the better where change is possible.


I’m following up to Wins and Losses.

Here’s the letter I sent declining the interview.

Hi 4— and 3–,

The conversation with 3– yesterday and 4—‘s follow-up about what {your university} is looking for have raised a few issues that make me doubt that the strengths I would bring to {your university} are what {your university} will value in the tenure and promotion process. Consequently, I think it is best that I decline the invitation for a campus interview at this time.

A longer explanation:

I think 3– knows that I think one of the leading strengths of my application is my ability to work with undergraduates on projects and, in particular, mentor undergraduate research, but this doesn’t seem to be well-placed in the tenure and promotion process at {your university}.

With 4—‘s letter: my current plan of research is interdisciplinary. We would expect publications in good journals, but not necessarily math journals. This, coupled with my conversation with 3–, leaves me wondering how I fit with what {your university} is really looking for.

I would welcome having the invitation revisited later if you feel that I am a better fit for your department than what I am currently seeing.

I also wish you best of luck in your search. Definitely keep doing the phone interviews; it is better for everyone if you interview and hire candidates that can give you what you want.

Best regards,

Dr. Jinx

You want to see flummoxed, the department chair (3–) and search committee chair
(4—) clearly weren’t expecting that. I got a 3 page email reply from the chair, and both urged me to reconsider.

Unfortunately, there was no more clarity in the 3 page email reply from the chair than there was in the initial phone conversation. This department wants undergraduate research and wants to raise its profile. They have no idea how it fits into their department. If it doesn’t produce peer-reviewed research papers in good journals, it really doesn’t matter for much of anything. Notice, we are discussing undergraduate research. If a publication in a good journal is 1/3 of the requirement for me for tenure, this is a fantastic accomplishment for an undergraduate and that undergraduate’s mentor.

And, as valued toward teaching if it doesn’t result in a peer-reviewed publication in a good journal, this is an uncompensated overload.

Not. Impressed.

I think I’ll send them a follow-up on Monday reiterating the problem and stating that this is the sort of mess I am good at cleaning up. I’ll followup that my hourly consulting rate is $250, and I would be happy to help them figure out how undergraduate research should be handled in their department and the tenure and promotion process. If they would prefer not to hire me given my relationship to their search, I would be happy to recommend a colleague.

Or maybe not. We’ll see how much energy I have over the weekend.

In any case, in reply to the previous blog post and follow up, a friend wrote:

I’ve got to tell you, I have been delighted by the thought of you turning down that interview. You are an academic badass Jinx! I hope I can be as good at listening to my intuition and going for what I want instead of whatever is offered to me when I return to the workforce.

You are a hero to me right now!

That made me feel good. I replied, “I think I’m going to have a hard time wiping that cocky smile off my face today.”

I needed it. Some controversy with the department came around to roost again. It appears once again, within my department, that I am mistaken and confused as to what my job duties are. Now, I am a careful and conscientious person. I think that repeated, documentable, problems with this, especially when I have produced evidence in writing about what I’ve been told are my duties that are in conflict with what others are telling the chair, should cause the department chair to stop, look, listen and, for goodness sake, think when given information that once again indicates that I don’t get what I’m supposed to do. Jehosophat.

And could we please take a moment and consider all the things I have done, the level of competence with which they have been done, and the once again, the documented lack of resources that I was given to get them done.

I should have some credit built up by now.

But I’m not tenure-track faculty. I don’t even get the courtesy extended to make me part of the conversation about my duties.

The department chair walked in when I was discussing these issues with my immediate supervisor. He tried to duck out quickly after asking his question. I didn’t let him. I let him know that

  1. That I, up until this year, did not want to leave Texas A&M, but I am now on the job market.
  2. The lack of clarity with regards to my duties is one of several reasons why I am on the job market. I can no longer see staying at Texas A&M.
  3. That lack of clarity, especially this repeated extenuating lack of clarity, in someone’s job duties is unacceptable to me and should be unacceptable to him as department chair.
  4. That while I liked him and was glad when he was first appointed chair, this is, in fact, an embarrassment to our department and calls into serious question the professionalism of our administration.
  5. The REU principal investigator threw me under the bus. And I am angry about this.
  6. I should be included in these discussions about what I am doing and what I am supposed to do.

I was polite, professional, and not about to brook any nonsense. He said I need to hear his side of it. In a meeting. Later. And ducked out of there.

I contacted the dean of faculties to inform them of the situation and request mediation at this meeting. Which is not yet scheduled. I wonder how many weeks this will take.

Academic badass. It was one hell of a stressful day. But bring it on. If we are going to fight this battle, we are going to fight this battle. I am going to do my best to get this crap straightened out for my colleagues’ sakes. Me, however, I think if I get any kind of an acceptable offer I am out of here in the fall. Maybe at the end of the spring.

Stress, burnout and advice

Sometimes I think I give too much advice. I like to give advice. I like to give good advice! But not everyone needs advice, sometimes people need empathy more than anything else. So I hope that my predilection isn’t a big negative on my listening skills. I hope it isn’t affecting them much at all, but I guess if I’m honest, I have to admit that it probably does, and I should be careful.

But there is one definite upside of giving advice, which is that if I find myself saying it to someone else, then I have to listen to it. Sometimes, the first time you can really hear something is when you find yourself saying it.

And most recently I found myself saying, “You have to take time for yourself. Study after study shows that a 40 hour work week maximizes productivity, especially for knowledge workers.”

I’ve been working some ungodly hours for most of the semester. More than 40? Sometimes more than 60 a week. I haven’t liked it, but I’ve felt like this is what I need to do to get everything done.

And maybe I slipped into that grossly unproductive zone where you are working and working at things and not really getting anything done. And making mistakes. I know I’ve made a lot of mistakes. The first exam proofreading was embarrassingly bad.

So. Stop. Stop it now. I am stressed. And I am feeling a lot of burnout. And you know what? I do not need to be a hero here. I’m afraid of not doing enough, but maybe that is stupid. If I did less, maybe I could do more.

And so, I need to try to take all or most of this next weekend off.

Don’t believe me? This web article is not perfect, but it discusses the relevant research.

It comes down to productivity. Workers can maintain productivity more or less indefinitely at 40 hours per five-day workweek. When working longer hours, productivity begins to decline. Somewhere between four days and two months, the gains from additional hours of work are negated by the decline in hourly productivity. In extreme cases (within a day or two, as soon as workers stop getting at least 7-8 hours of sleep per night), the degradation can be abrupt.

Many of the studies quoted above come out of industrial environments, and it may be argued that the more creative mental work of programmers, artists, and testers is fundamentally different. In fact, it is different , and Colonel Belenky explicitly addresses that:

In contrast to complex mental performance, simple psychomotor performance, physical strength and endurance are unaffected by sleep deprivation.

The ability to do complex mental tasks degrades faster than physical performance does. Among knowledge workers, the productivity loss due to excessive hours may begin sooner and be greater than it is among soldiers, because our work is more affected by mental fatigue.
