When you're a fledgling youth-type adult, it appears that all people in their 40s look old enough to be in a painting hanging on the wall of a stately home in England. It's not until you limp into your 70s that people in their 40s look too young to vote, and college cheerleaders closely resemble Yorkshire terriers.

I always wanted to be a surgeon, because I had a lot of admiration for my father, who is also a surgeon. I also wanted to be a heart surgeon. That was motivated by the fact that my young aunt, a sister of my dad, died in her early 20s of a correctable heart disease.
