I've noticed that most men in their 50s and 60s talk about it constantly and are always trying to get a pill or two sample from their MDs (I work around hundreds of guys and my last SO is 61). Sad, though.
It's a little scary, because many guys 50+ take some sort of cholesterol or BP medication and too many have heart attacks.
If you don't think he needs it and his doc didn't recommend it, you may want to try to ask him to save it. Take care of your man, okay?
