body odor

So, yeah....not sure how to explain this. Hmmm...
Alright, let's set up the scenario.

You go to work, which happens to be a funeral home at the moment. Not a bad place, it's money. No, the answer is you don't have to touch the bodies if you don't want to. You will see them often though. Let's get back to it. You're at work. You answer a few phone call that more often than not start with.."I know this is a weird question but..." Pretty soon, your nose starts to twitch. You can smell something, but you're not quite sure what it is. It's a foul odor, somewhat like somebody didn't quite shower this morning...or for about a month for that matter. You look around. No one else is around you. Suddenly you're a bit embarrassed. Is it you? You smell your hair, nope (smells like flowery shampoo). You're pretty darn sure it is not you. So you start to investigate your desk...what could it be?
"You smell that?" One of your coworkers notices your search.
"Uh, yeah, what is that?" You reply a little sheepishly.
"You didn't hear? Body in the viewing room. Smell is coming from the other side of your wall."
If there was a light over your head, it would have turned on by now.
As quickly as the light goes on, it begins to dim...
There is a rotting body emitting toxic fumes into your space...
Great.
