“It is a relatively recent phenomenon that human beings worry about old age, social security, medical bills, and long-term care. But you can only plan so much. In general, things either work out or they don’t, and if they don’t, you figure out something else, a plan B. There’s nothing wrong with plan B. Most of life, as I have learned, is a plan B. Or a plan C. Or plans L, M, N, O, P.”
