Evolution Is Moving Us Away from Selfishness. But Where Is It Taking Us?

Renowned medical researcher Dr. Rudolph Tanzi takes you on a tour of the brain, and explains why positive thinking might be the best gift you can give your genes this holiday season.

Surprising Science

We live in our emotions, explains renowned medical researcher Dr. Rudolph Tanzi. Our emotions and overall outlook on life correspond to different parts of the brain. How you decide to approach your life determines which parts of your brain become activated. If you allow fear and worry to rule you, the brain stem is exercised. If you embrace things like creativity, empathy, and community, you activate the frontal cortex. These decisions — the choices you make in how you want to life — have a direct effect on your genetic activity. That's why positive thinking might be the best gift you can give to your genetic dependents.

Dr. Tanzi, a Professor of Neurology at Harvard, is co-author of the new book Super Genes: Harnessing the Vast Potential of Your Genome for Optimum Health and Well-Being.
