I’m guessing the turn your head part is so that you don’t cough on the doctor’s head. But what does the rest of the test tell him?
For the ladies
This is a test that men go through for some strange reason. I had to do it before I was allowed to play football in the 7th grade. A doctor places two fingers under your testicles and then you are instructed to ‘turn your head and cough’. How this determined that I was fit to play football, I don’t know.
