Remember to massage your internal organs
"Laughter involves every major system in the body. Your diaphragm convulses, causing all internal organs to be massaged. Your muscles relax; your blood is highly oxygenated. You enhance your cardiovascular flexibility."
Sure beats running on a treadmill.
Here's something else from today's DMN story about the medicine of laughter:
"Once you realize laughter is a chemical process that rebalances the chemistry of fear and anger and boredom, laughter is appropriate anywhere there is stress, tension or pain."
Tell this to your boss when you laugh at him during a job evaluation. If he's laughing at you, well, just try to convince yourself it's because he's stressed out about calling you "incompetent."
