Old-Person Smell Is Actually A Thing, And Here’s Where It Comes From

As people advance in age, their rates of metabolism change drastically. The Skin is the largest organ in the body, which is significantly affected.

This is a catabolic reaction which releases odoriferous molecules into the atmosphere around elderly people. Several researchers have concluded that the most highly-secreted chemical causing this smell is a compound called 2-nonenal, released from the breakdown of fatty acids by oxygen.
