Giggle

Laughter triggers the release of endorphins, those chemicals in the brain that induce feelings of euphoria. A good giggle can also suppress the production of corticol, a hormone released when you're under stress and one that can influence blood pressure, causing your body to retain salt. Laughter is legal, moral and non-fattening. Laughter, and better yet a good giggle, is also contagious, and engaging in laughter frequently will contribute to a happier world around you.
