We talk about this a lot on HN, and I'm curious: Are there good studies on this stuff /in the programming context/? I'm aware of the work with athletes and musicians (an excellent start, but requires a lot of generalization to corporate knowledge work). Even better, given that people are going to vary by at least as much as we vary in physical stamina, advice about how to learn what my own limits are, given that it's so hard to introspect?
