Video: James Fowler and Dean Ornish

How long should you walk during a week to grow brain cells? Can your friends’ friends impact your health?

We’re releasing two videos this week from PopTech 2009 on how networks affect personal health: Dr. Dean Ornish and James Fowler.

Thoughts? Let us know in the comments.

For more than thirty years, Dr. Dean Ornish has demonstrated the power of a healthy lifestyle as the best kind of preventive care. These choices, Ornish reveals, can "turn on” disease-preventing genes and “turn off” genes that promote illness. Dr. Ornish has published a number of best-selling books on the subject; the most recent is The Spectrum.

- Dr. Ornish on WebMD, on Facebook, and Twitter @DeanOrnishMD.
- Attend Imagine Solutions conference with Dr. Ornish, Feb 22-3 in Naples, Florida.
- Visit Preventative Medicine Research Institute forums (Dr. Ornish is Founder and President).


Can your social network make you fat? Affect your mood? Political scientist James H. Fowler reveals that social networks have clusters of happy and unhappy people within them. With Nicholas A. Christakis, Fowler recently co-authored, Connected: The Surprising Power of Our Social Networks and How They Shape Our Lives.
