I have developed a unique way of looking at the relationship of the human body to health and disease.

If your DNA profile puts you at a higher risk of developing obesity, that doesn't mean it's your fate. You can take control of the environmental side of the equation and reduce your overall lifetime risk by a lot.

Cancer is the ultimate nemesis that hangs in the balance for one in three women and one in two men in their lifetime.

I'm a big believer in what's called personalized medicine, which refers to customizing your health care to your specific needs based on your physiology, genetics, value system and unique conditions.

We all need to figure out what's right for us because nothing about life is one size fits all. Even for an Olympian, that's for sure. And such discovery starts with you paying attention - to yourself.

In health care today, we spend most of the dollars - in terms of treating disease - in the last two years of a person's life.

No technology will win. Technology itself will win.
