It shouldn't surprise anyone that countless hours-per-day held in a static posture is right there with repetitive motion in terms of health consequences. Both are a kind of bizarre thing to do, and it's hard to imagine that human evolution had much opportunity to optimize for any particular sustained posture or deeply repetitive motion when much broader variety seems to be the norm throughout most of culture and history. You wouldn't expect an hour of doing something else, however vigorous or dynamic, to really overcome the consequences of such a contrived routine. If you want care about this stuff (it's fair not to; you'll still live as long as your peers if you don't), you do just need to figure out how to make frequent, non-repetitive movement part of your day.

That we didn't evolve to read doesn't mean I don't enjoy a book or it can't be healthy for me to relax in that escape. This is not a useful predictor for whether or not something is healthy

  If you read books 10 hours a day you will get myopia (shortsightedness)

    Citation needed. Per my understanding, this is false because, while the correlation is there, tests for causality fail to find support for this hypothesis. Newer studies seem to point to sunlight, perhaps it is due to different wavelengths or perhaps to the light's intensity that isn't sufficient indoors—where one often reads books, but not necessarily, and so the reading of stories doesn't seem to be myopia's cause Unless it turns out to be a constant focal point (such as on a book) after all, this is the same fallacy as the person I was responding to: sure, many unnatural things are bad for us because we are indeed not selected for ("made") to cope with it, but that's not the cause of why it's bad for us. At best, it can be a rule of thumb where no further information is available (like to answer "is this chemical only occurring on Ganymede edible?", you can use the rule to say "doubt it", but not to dismiss the idea of a study being useful by saying like the person above "who expects it to be healthy? It's such a bizarre thing to do")

How many hours do you sleep per day?

  I certainly don't sleep in one position all night, if that's what you mean. Not unless I took something strong and exogenous to knock me out, which also seems like a questionable habit. If I did stay in one position, I'm sure my back would be killing me by morning, my neck would have a nasty crick in it, and my arm would have a fallen asleep and woken me up a half dozen times.
