Did you know that your body is capable of segregating a drug that is hundreds of times more potent than heroin or morphine and that has no side effects. Endorphins, powerful biochemical analgesics segregated by the brain, are one of the most significant scientific discoveries in the history of medicine. Massage, sports, music, and especially doing what we enjoy doing, prompt our body to manufacture endorphins. Their proper flow throughout our body makes us feel good. Happiness is a biochemical state we can all achieve, and endorphins are drugs that make it possible.
