Following up on yesterday’s post about biogerontologist Aubrey de Grey, an excerpt from “The Invincible Man,” a 2007 Washington Post profile by Joel Garreau of the scientist who believes we can conquer aging:

“At midday in George Washington University’s Kogan Plaza off H Street NW, you are surrounded by firm, young flesh. Muscular young men saunter by in sandals, T-shirts and cargo shorts. Young blond women sport clingy, sleeveless tops, oversize sunglasses and the astounding array of subtle variations available in flip-flops and painted toenails.

Is this the future? you ask de Grey.

‘Yes, it is precisely the future,’ he says. ‘Except without people who look as old as you and me.’

‘Of course the world will be completely different in all manner of ways,’ de Grey says of the next few decades. His speech is thick, fast and mellifluous, with a quality British accent.

‘If we want to hit the high points, number one is, there will not be any frail elderly people. Which means we won’t be spending all this unbelievable amount of money keeping all those frail elderly people alive for like one extra year the way we do at the moment. That money will be available to spend on important things like, well, obviously, providing the health care to keep us that way, but that won’t be anything like so expensive. Secondly, just doing the things we can’t afford now, giving people proper education and not just when they’re kids, but also proper adult education and retraining and so on.

‘Another thing that’s going to have to change completely is retirement. For the moment, when you retire, you retire forever. We’re sorry for old people because they’re going downhill. There will be no real moral or sociological requirement to do that. Sure, there is going to be a need for Social Security as a safety net just as there is now. But retirement will be a periodic thing. You’ll be a journalist for 40 years or whatever and then you’ll be sick of it and you’ll retire on your savings or on a state pension, depending on what the system is. So after 20 years, golf will have lost its novelty value, and you’ll want to do something else with your life. You’ll get more retraining and education, and go and be a rock star for 40 years, and then retire again and so on.’

The mind reels. Will we want to be married to the same person for a thousand years? Will we need religion anymore? Will the planet fill to overflowing?”
