Rochester, Minnesota - "Research shows laughter provides a good physical workout, generates mental relaxation, lowers blood pressure and pain, and even improves immunity. You’re 30 times more likely to laugh in good company than alone. Further, the more you laugh with others rather than at someone, the greater the health benefit." - Dr. Amit Sood.

Dr. Amit Sood, is director of research in the Complementary and Integrative Medicine Program at Mayo Clinic in Rochester, Minn. He also chairs the Mind-Body Medicine Initiative at Mayo Clinic.
