The 20th-century ulcer epidemic was a sign of good health in American people - good diet, strong acidity and healthy immune response actually make ulcers more likely. That's why businessmen eating giant T-bone steaks were prone to ulcers.

In medical school, it's quite possible to get taught that you can diagnose everybody and treat everything. But then you get out in the real world and find that for most patients walking through your door, you have no idea what's causing their symptoms.

Dad always explained the car engine when he repaired it, and he had many technical books, so I was making electromagnets by age eight as well as reading my mother's medical and nursing books. I suspect I was born with a boundless curiosity, and this was encouraged through my childhood.
