Surely, sport is not fundamentally about the safety of athletes. If it were, we'd probably have to ban professional football, right after boxing.

You can't go into new life experiences without the understanding that yeah, you may fail, but knowing you might fail can't stop you from trying.

Using medicine in the service of cosmesis is generally bad for patients, bad for doctors, and bad for democracy. The only exceptions are when we know the intervention will actually reduce suffering, as with a primary cleft lip repair.

About 25 years ago, my wife and I bought Kenny Loggins' house in Santa Barbara. It was way out of our price range, but we said, 'Screw it, let's go for it.' We've raised our family there. We overextended ourselves at the perfect time in our lives, and it worked out for the best.

Nobody just leaves medical school, especially given it's fiercely competitive to get in. But I had a sister who was a doctor, another who was a pharmacist, a brother who was an engineer.
