Medicine grounds me, it centers me, that's why I continue to do it.

In my business, if I get too close to you and you die, it hurts me. And so you develop a natural inclination not to be close to the patient, so that if things don't work out ideally, you can still get up the next day and care for the next patient.

Our ancestors had to eat whenever food was around. And we're actually still hardwired the same way. The big difference is we don't have to hunt for our food. For us, "hunting" comes down to sliding the milk carton out of the way.

We're all human beings, but some of us are more sophisticated at covering our flaws. We're just smart enough to lie to ourselves that everything is OK.

Medicine has always been my calling.

Avoid buying frozen dinners and processed foods, as they are often overloaded with salt.
