My sister in law's husband!
He's a Consultant Gastro-Enterologist - Endoscopies(and Gastroscopies)-R-Us! he decided to study it because there was a shortage of them 40 years ago in the UK, and he thought it would be easy to get work. Unfortunately, so did a lot of other people!

He said that one of the worst things was having to carry one's own "samples" to uni on the bus....
