How Does the Sense of Smell Affect Your Mind?

It can make you psychic.

We can feel fear, joy, desire, and other emotions just from another person’s scent. It happens because human sweat and tears contain chemosignals. Each chemosignal activates a different section of our brains. So if the other person’s afraid, his sweat tells our brains he feels that way which causes the “fear” section of our brain to become exposed to it.
