I used to be like this back when I chronically under-exercised, it was the only thing that would help me sleep. And even then, I struggled with insomnia.

Personally I need 10-20 hours of real sport a week to function really well, which seems to put me in some very high percentiles on HN. I need so much sport that I barely have time to do anything besides work and exercise, which means I don't do many non-athletic hobbies anymore.
