I think anybody that is challenged daily with alot of problem solving and creative thinking should have a psychical hobby. Sports like running or swimming are pretty inexpensive and give you a great work out. Personally my favorite hobby is tennis, not only does it require psychical fitness but also a vast amount of critical thinking. Strategy is key in this sport.

However any psychical activity not related to your daily job helps not only clear your mind but also stay in good shape. By all means, if I could require each developer that I work with, run 2 miles every other day without hesitation, I would it.
