When I was a kid (the Boss will probably argue that I haven't got past that stage yet), I wanted to be all the things a normal boy wants to be when they grow up. A fireman, a policeman, a soldier, even a famous footballer. I have to admit that being a paramedic was no where in the line-up. Probably because I was the most squeamish person you've ever come across.
I did however, strongly consider becoming a train driver. At least I now know why I didn't go with that one.
