When I’m Sixty-Four – The Age of Longevity

It is probably wise to take Thiel’s idea of an end to aging (or at least its radical postponement) seriously.

It does not seem that long ago that the Beatles could plausibly portray geriatric redundancy as beginning at an age sometimes referred to as young these days. “Will you still need me,” they asked, “Will you still feed me, when I’m sixty-four?”

That was, in fact, a while back — in 1967. But such is the mist cast by advancing years that it is hard to believe we stand close to a half-century from the Sgt. Pepper’s Lonely Hearts Club Band album. Since then life spans have grown dramatically in an acceleration of the process that has seen longevity double in developed countries over the past 150 years. In 1850, half of England’s population was dead by 45. Today, according to Sarah Harper, a British gerontologist, half the English population is alive at 85.

But these advances brought on by antibiotics, vaccination programs, improved sanitation and better medicine (not to mention dietary supplements and the treadmill) are peanuts compared to what may lie in store. The brave new world of regenerative medicine is upon us. This is the term of art for the various techniques and technologies (including cell therapy, gene therapy and tissue engineering) that will, its advocates say, allow the body to slow, halt or even reverse aging by enabling the regeneration and repair of damaged organs, cells and tissues. Talk of routinely living to 120 or even 200 no longer lies in the realm of cranks and fantasists.

Indeed, the buzz around radical life extension is such that the dot-com gurus who brought us the likes of Google and PayPal now find themselves laser-focused on an Age of Longevity, as if transforming our lives was not enough whereas doubling them through moonshot thinking would be an incontrovertible contribution to human progress. Connectivity was O.K., but conjuring super-centenarians will be better. Larry Page, the chief executive of Google, and Peter Thiel, the Silicon Valley billionaire, early investor in Facebook and co-founder of PayPal, are among those who, in separate ventures, have aging in their cross hairs.

“If people think they are going to die, it is demotivating,” Thiel told me. “The idea of immortality is motivational.” He described his ideas as “180 degrees the opposite” of Steve Jobs’s, who once said: “Remembering that you are going to die is the best way I know to avoid the trap of thinking you have something to lose. You are already naked. There is no reason not to follow your heart.”
