Well this thread has gone to $hit!
I asked my bother in law, a doctor, how doctors learn prostate exams. He said just how they learned to give injections, on each other... I thought. I asked if they found many bad prostates in a group of 21-24 year olds. He said there was usually one in the class. Then everybody had to learn what a bad one was like.
I feel sorry for that Med student!
