But, as with most guys, they do what their doctors say and don’t question it. Even on this forum, guys indicate that whatever their doctors say to do, they do……they explicitly trust whatever their doctors say….and that they’re putting their lives in their doctors’ hands.

That probably is not the best way to do things.
