Aging: Dying Young As Late As Possible

Henry Alford believes that old people are wise. And to prove it, he interviewed many people over the age of seventy, including Phyllis Diller, Harold Bloom and a retired aerospace engineer who eats food out of the garbage. The result is Alford's new book, "How to Live: A Search for Wisdom from Old People (While They Are Still On this Earth)." In this hour of To the Best of Our Knowledge, Henry Alford shares the age-old wisdom he received. Also, David Greenberger and the art he creates out of his conversations with older people.
