The "feel good" chemical serotonin is responsible for the brain's mood and is 80-90% found in the gastrointestinal tract. Mmm...food...always makes me happy... chocolate, pizza, deep fried...oh ya I'm in the middle of writing a description. Every time we laugh, we produce serotonin. So wear this heart shaped signet ring, put on a good comedy, cozy up on the couch, and laugh it up until you feel so good you never forget to love your badass self.
