What does the smell of dead bodies at home indicate?

This is a very inappropriate metaphor, and there is no scientific basis to prove this statement.

Corpse odor is a very unpleasant smell, which is produced by the decomposition of corpses. This smell is very bad, and it will get worse with time.

If you smell a corpse at home, I suggest you ventilate as soon as possible and pay attention to hygiene. If you are worried about any problems at home, please contact professionals for testing and maintenance in time.
