Not only do you have to look at and touch people's bits, but you have to mess around with dead bodies during your training. We have it on good authority, from a friend of ours, that "the smell stays with you".
Still. One company in Tampa, Florida, is offering an alternative to trainees who'd rather not flay a corpse for their shits and giggles; synthetic medical cadavers. Unfortunately, these cadavers are so realistic that they're virtually indistinguishable from the real thing.
Consequently, we recommend you go and do something else rather than look at them. No, really. This list is in no way going to improve your day.
