“The first thing I do is run faster on the uphills. Everyone else slows down because of how difficult it is, and this is a great time to gain ground. The second thing I do is run faster on the downhills. Everyone else slows down because of how fast you go anyways on the slope down, and this is a great time to gain ground.”
Conjecture from personal life: one reason I almost never (maybe once a year?) get noticeably/symptomatically sick may be that when I do get sick, I don’t perceive it as a reason to give myself a break, work less, skip exercise, etc. Maybe “the body learns that getting sick doesn’t pay off, so why get sick?”. There is some evidence that the onset of sickness symptoms is partially neurally mediated, so this kind of learning is at least plausible (ref).
