“The act of laughing releases some nice chemical into your brain, you feel good and it's free.”

“Infatuation doesn't last because it's conditional and conditions change, but if it's real love, it turns into mature, unconditional love, and new chemicals are released in the brain, Endorphins that make you feel warm and peaceful and satisfied and content whenever you're with the one you love.... And miserable when you're without him because if he's not there, the brain won't produce chemicals.”

“Serotonin, the "feel-good" brain chemical that is boosted by Prozac, depends on magnesium for its production and function.”

“Your brain is doing some great work when it's laughing.”

“We both laugh. And it feels good. A release. Like laughing at a funeral. Maybe inappropriate, but definitely needed.”

“Your body produces some chemicals that stimulate some nerves that send a signal to your brain saying 'Oh my God, I am going to die,' and that's how you get pain.”
