I agree, physical exercise is really important. In addition to the usual exercises (walking, weight training, etc), don't forget the ones that are only available to PCa folks like us.
My favorite is the Midnight Obstacle Course, where the object is to race from bed to bathroom, in the dark, while doing the "Kegel Hop". I'm thinking of timing this run, with penalties assessed for crashing into furniture, waking family members, and of course a big penalty for not getting to the toilet in time.
Any other ideas? Maybe we could organize a PCa Olympics...
