The hardest question for anyone who takes responsibility for what he or she does is, What if I turn out to be average? - Atul Gawande

Good checklists, on the other hand, are precise. They are efficient, to the point, and easy to use even in the most difficult situations. They do not try to spell out everything — a checklist cannot fly a plane. Instead, they provide reminders of only the most critical and important steps — the ones that even the highly skilled professionals using them could miss. Good checklists are, above all, practical.

Assisted living most often became a mere layover on the way from independent living to a nursing home. It became part of the now widespread idea of a “continuum of care,” which sounds perfectly nice and logical but manages to perpetuate conditions that treat the elderly like preschool children. Concern about safety and lawsuits increasingly limited what people could have in their assisted living apartments, mandated what activities they were expected to participate in, and defined ever more stringent move-out conditions that would trigger “discharge” to a nursing facility. The language of medicine, with its priorities of safety and survival, was taking over, again. Wilson pointed out angrily that even children are permitted to take more risks than the elderly. They at least get to have swings and jungle gyms.

IN 1908, A Harvard philosopher named Josiah Royce wrote a book with the title The Philosophy of Loyalty. Royce was not concerned with the trials of aging. But he was concerned with a puzzle that is fundamental to anyone contemplating his or her mortality. Royce wanted to understand why simply existing — why being merely housed and fed and safe and alive — seems empty and meaningless to us. What more is it that we need in order to feel that life is worthwhile? The answer, he believed, is that we all seek a cause beyond ourselves. This was, to him, an intrinsic human need. The cause could be large (family, country, principle) or small (a building project, the care of a pet). The important thing was that, in ascribing value to the cause and seeing it as worth making sacrifices for, we give our lives meaning.
