ELI5: Why do people put cologne/perfume on the insides of their wrists?
gpt
I've heard 2 explanations - can't vouch for either.

1. Wrist have a lot of blood flow near the skin and hence produce a lot of heat. Heat helps release the scent.

2. Wrists are an area that are likely to get closer to other people. Guess they also always exposed where much of the body isnt.
