13: Dr. Michael Miller: How to Prevent Heart Disease

“If there's a good laugh, then you get tears to come down [from] your eyes. You feel great and it's because of the release of chemicals, such as beta-endorphins. And then it activates other blood chemicals in the cardiovascular system [like]: nitric oxide. And this kind of tag team, if you will, appear to really lead to the beneficial effects on the blood vessels.” – Michael Miller is a best-selling author, professor of cardiovascular medicine at the University of Maryland School of Medicine, and an innovative researcher in heart disease prevention.
