I also definitely enjoy non-programming time. Don't get me wrong, programming (especially in Perl) is a joy, but unless I'm in a zone, it's hard to sit still for more than an hour or so at a time. Frequent 5- to 10-minute breaks really boost my productivity by allowing my brain to rest and recuperate just a bit. Simply using Perl also boosts my productivity, since most programming can be done more quickly in Perl than other languages.
But anyway, I agree that there are many other things in life to be enjoyed. I'm also a chessplayer, an avid reader, a church-goer, a husband and soon-to-be father... and work is definitely a secondary priority to my family. I think it's great to round out one's time doing something other than coding.
