Note the timelines they are talking about. 17 years from today. If I live that long, I'll be 87, and more than likely in an old folks home gumming a stale sandwitch, and swigging down a glass of 2% milk and a dose of Geritol.

By that time...87 will be the new "60" so you will still be doing handstands and racing down the highways
