It’s called brown adipose tissue aka brown fat. Old people are always cold because they often lack brown fat.
That's why I'm storing up on brown fat in my youth.
Don't non-baby humans lack brown fat in general?
Not really. Babies have brown fat as default. Adults have white fat which can turn brown in response to cold exposure (not as much as in babies, so it's also called beige fat). Brown of beige though, it works the same - there's a high count of mitochondria in the cells and the tissue can produce heat and make you feel (and be) warmer. It also helps with weight loss, stimulates the immune system and lowers inflammation.
