“I have been aware for many years that most people do not think about aging in the same way that they think about cancer, or diabetes, or heart disease. They are strongly in favor of the absolute elimination of such diseases as soon as possible, but the idea of eliminating aging – maintaining truly youthful physical and mental function indefinitely – evokes an avalanche of fears and reservations. Yet, in the sense that matters most, aging is just like smoking: It’s really bad for you.”
