we usually have only vague indicators to rely upon. - Atul Gawande

What geriatricians do — bolster our resilience in old age, our capacity to weather what comes — is both difficult and unappealingly limited. It requires attention to the body and its alterations. It requires vigilance over nutrition, medications, and living situations. And it requires each of us to contemplate the unfixables in our life, the decline we will unavoidably face, in order to make the small changes necessary to reshape it. When the prevailing fantasy is that we can be ageless, the geriatrician’s uncomfortable demand is that we accept we are not.

Whereas today people often understate their age to census takers, studies of past censuses have revealed that they used to overstate it.

attending surgeons say that what’s most important to them is finding people who are conscientious, industrious, and boneheaded enough to stick at practicing this one difficult thing day and night for years on end. As one professor of surgery put it to me, given a choice between a Ph.D. who had painstakingly cloned a gene and a talented sculptor, he’d pick the Ph.D. every time. Sure, he said, he’d bet on the sculptor being more physically talented; but he’d bet on the Ph.D. being less “flaky.” And in the end that matters more. Skill, surgeons believe, can be taught; tenacity cannot. It’s an odd approach to recruitment, but it continues all the way up the ranks, even in top surgery departments. They take minions with no experience in surgery, spend years training them, and then take most of their faculty from these same homegrown ranks.
And it works.
