Your Body Odor Can Reveal Your Age

People can tell how old you are by how you smell, according to new research published in the journal PLoS One.

It appears that “old person smell” some people complain about is for real, that elderly people emit a unique identifying odor.

An elderly individual's "old person smell" is actually acknowledged and accepted in cultures throughout the world. In Japan, there's a special word, kareishū, that describes it.

Funny thing though, according to the research, all age groups rated "old person smell" as less intense and less unpleasant than the body odors of middle-aged and young individuals.
