Doc,

I’ve seen a lot of tv commercials for men who have trouble or a feeling of urgency to urinate. If my PSA is low, what do you think is the most likely cause and what course of action do you suggest?

As I get older, now 65, I find that excercise is causing me to get minor injuries. If it isn’t a sore back after yoga then it’s a sore achilles tendon after walking on the treadmill. Other than swimming, what excercises can you suggest that are suitable for a guy who thinks he’s in ok shape?
