“Medical science deserves hearty congratulations for extending the lifespan of Americans to 80 years and beyond. This is truly an impressive feat, considering that most babies born in 1900 did not live past the age of 50. I rejoice in my own longevity, as I’m sure you do. But I also wonder whether the same health care system that gave me these extra years is doing its best to help me make sure those years are healthy ones. Frankly, I have my doubts.”
