Laugh it up

This one's been researched by psychologists and hard scientists alike for years now, but a little reinforcement from Scientific American never hurts:

"Laughter relaxes us and improves our mood, and hearing jokes may ease anxiety. Amusement’s ability to counteract physical agony is well documented, and as Cousins’s experience suggests, humor’s analgesic effect lasts after the smile has faded.
Cheerfulness, a trait that makes people respond more readily to laugh lines, is linked to emotional resilience—the ability to keep a level head in difficult circumstances—and to close relationships, studies show. Science also indicates that a sense of humor is sexy; women are attracted to men who have one. Thus, in various ways, life satisfaction may increase with the ability to laugh."

And now for something to make you LOL:
