Warfarin is the drug the medical community loves to hate.

I have had my genome fully sequenced and have learned a great deal about which medications I would respond to and which might or would induce major side effects, along with knowing many medical conditions for which I'm particularly susceptible.

Chemotherapy is just medieval. It's such a blunt instrument. We're going to look back on it like we do the dark ages.

The problem is that it takes physicians so long to accept a radical change. And the lag is unacceptable.

I use a portable pocket ultrasound device instead of a stethoscope to listen to the heart, and I share it with the patient in real time. 'Look at your valve, look at your heart-muscle strength.' So they're looking at it with me. Normally a patient is tested by an ultrasonographer who is not allowed to tell them anything.

For people who have heart disease, statins are great. But if all you've had is high cholesterol, what you're doing is taking this 1/100 chance of getting a benefit and offsetting it with 1/200 chance of getting diabetes.

For diabetes in particular, we know there's a relationship between lack of glucose regulation and complications like blindness and kidney failure. So if you were diabetic and you knew that you could get your glucose in a tight, normal range just by adjusting your lifestyle, wouldn't that be great?
