@Ceili,
We used to laugh in our academic world when we heard that American universities had degrees in golf. Oh--30 or more years ago.
Now Americans design and build most of the world's golf courses for fees which would make the eyes of an innocent like you water.
I once taught organic chemistry in a university and I was asked to introduce a class of up and coming hairdressers to the elementary scientific aspects of their trade. It really was very interesting and three of the better lookers persuaded me to let them practice on my head on one of my afternoons off.
