What do you think the worst smell is?

Sulphur dioxide has a pungent smell.

The smell of a human body is worse than the smell of a dead rat.

I think the worst smell is from the decayed dead human body or from any dead animal, that has been in an area, for a long period of time.

Skunk. If you ever encounter one close up…you can’t breathe it’s so bad and the smell gets on you too.

I use to live across the street from a turkey plant and a farm with cows. Such an awful smell. Had to keep deodorized air freshener, incense, anything to keep the air in the house smelling good.
