Our survival depends on the healing power of love, intimacy and relationships. As individuals. As communities. As a country. As a culture. Perhaps even as a species.

I usually find that the process of discovery is more interesting than the answers.

The Internet has transformed many parts of our daily lives, touching everything from how we find information to how we go shopping, get directions, and even stay in touch with friends and family.

One of the reasons my father ... became a dentist was so he could always be home for dinner and spend weekends with his family. At one point he had thought about being a musician, but he said, I'm not going to do that because I'd be on the road all the time and I wouldn't be with my family.

People who are lonely and depressed are three to 10 times more likely to get sick and die prematurely than those who have a strong sense of love and community. I don’t know any other single factor that affects our health - for better and for worse - to such a strong degree.

Think about it: Heart disease and diabetes, which account for more deaths in the U.S. and worldwide than everything else combined, are completely preventable by making comprehensive lifestyle changes. Without drugs or surgery.

Love and intimacy are at the root of what makes us sick and what makes us well...I am not aware of any other factor in medicine-not diet, not smoking, not exercise-that has a greater impact.
