Death is the enemy. I spent 10 years of my life singlemindedly studying, practicing, fighting hand to hand in close quarters to defeat the enemy, to send him back bloodied and humble and I am not going to roll over and surrender.

Life is everywhere. The earth is throbbing with it - it's like music. The plants, the creatures, the ones we see, the ones we don't see, it's like one, big, pulsating symphony.

I guess what I'm trying to say is I don't think you can measure life in terms of years. I think longevity doesn't necessarily have anything to do with happiness. I mean happiness comes from facing challenges and going out on a limb and taking risks. If you're not willing to take a risk for something you really care about, you might as well be dead.

As a scientist, I am not sure anymore that life can be reduced to a class struggle, to dialectical materialism, or any set of formulas. Life is spontaneous and it is unpredictable, it is magical. I think that we have struggled so hard with the tangible that we have forgotten the intangible.

I am going to concentrate on what's important in life. I'm going to strive everyday to be a kind and generous and loving person. I'm going to keep death right here, so that anytime I even think about getting angry at you or anybody else, I'll see death and I'll remember.

Let's not kid ourselves. Whatever we diagnose, most patients, if they don't die, get well by themselves. Our job is mainly to try to make them feel better; do no harm.
