I'm a big admirer of Walter Willett's work. I think he's done some really important research. He and I agree on most things.

Whether you're six or sixty, if you go on a diet and lifestyle program and feel constrained, you're likely to go off it sooner or later. Offering a spectrum of choices is much more effective; then, you feel free and empowered.

I grew up in Texas, eating meat five times a day, and I liked meat. But I began being a vegetarian when I was 19 because I found that I felt better.

Whether it's by helping us search for health-related information, connecting us with doctors through online portals, or enabling us to store and retrieve our medical records online, the Internet is starting to show the promise it has to transform the way people interact with and improve their own health and wellness.

Over time, years of meditation gave me glimpses of the interconnectedness and interdependence of all life. I experienced that on one level we are alone, separate, apart from everyone and everything; on another level, we are the Self in different disguises, different names and forms, a part of everyone and everything. This experience of interconnectedness is part of spiritual traditions and the perennial wisdom in virtually all religions and cultures.

Joy of living is sustainable; fear of dying is not.
