I've never met a great programmer than didn't also love other stuff besides programming. Variety is the juice that creativity runs on.
Can't find any examples just right now, but the mentality of "I am a programmer and I want more time away from programming" seems to be everywhere at the moment, I don't get it. Not so much "why do people love other things", but "why don't programmers love programming as much as other they love other things".
(I am a guitar player and would die without 1-2 hours of jamming every couple of days, just so you know I'm not lying, I can love other things as well! :P)
