Physical Danger
Zombies.
No - just kidding. Surprisingly, however, if you aren't careful and don't take your time, you could, through fault of your own, end up with a chemical burn because you forgot to put the cap back on the bottle of embalming fluid. You could end up with all sorts of physical and mental problems, including depression and obesity, if you don't learn to manage your stress properly. Or you could receive a broken rib from all the hugs families are going to want to give you.
However, all that can be negated, or at least lessened, with a little help from your friends - or, in this case, co-workers. Hopefully they'll become people you can call friends. After all, a friend helps you move, but a real friend helps you move dead bodies.
