Porcelain people that shatters at the minimum problem crying rivers of drama are not prepared to do this kind of work for sure.

But the fact beyond this caricature is that most of the women and men that work in a lab never develop a phobia towards blood, accept that dealing with death is part of the life, and don't have problems or "emotional tools" with the idea of breeding animals.
