Feel like smiling? Great, your immune system is getting a boost. Feel like a bit of a bellylaugh? Wonderful, your pain tolerance just shot up. Seriously, laughter can do some really serious good for your body and your mind and your spirit and your health.

Really, want someone to feel less pain? Tell ’em a joke, a good one.
