"The idea of living to be 95 scares the bejesus out of me (yes – almost more than the thought of dying). If there were conclusive proof that exercise could make you live to such advanced ages, I suspect it would become much less popular. 60 years of solid debauch is all I’ve ever aspired to. Although, of course, when you hit the last quarter of that span, you start a panicky reappraisal."
