“If I had known I was going to live this long I’d have taken better care of myself.” It’s a quip attributed to, among others, Mark Twain, Jimmy Durante and George Burns – and one reason it’s so popular is that there’s truth in it. Burns cracked that joke on his 99th birthday but, for most of us, wondering how long we’ve got to live is no longer the key question, at least not for affluent westerners, whose life expectancy has risen steadily.
