Living to be 1000 (years old)

Bootstrapping our way to an ageless future by Aubrey de Grey

Biomedical gerontologist Aubrey de Grey expects many people alive today to live to 1000 years of age and to avoid age-related health problems even at that age. In this excerpt from his just-published, much-awaited book, Ending Aging, he explains how.

Bootstrapping our way to an ageless future

I have a confession to make. In Chapters 5 through 12, where I explained the details of SENS, I elided one rather important fact—a fact that the biologists among my audience will very probably have spotted. I'm going to address that omission in this chapter, building on a line of reasoning that I introduced in an ostensibly quite circumscribed context towards the end of Chapter 9.

It is this: the therapies that we develop in a decade or so in mice, and those that may come only a decade or two later for humans, will not be perfect. Other things being equal, there will be a residual accumulation of damage within our bodies, however frequently and thoroughly we apply these therapies, and we will eventually experience age-related decline and death just as now, only at a greater age. Probably not all that much greater either — probably only 30-50 years older than today.

But other things won't be equal. In this chapter, I'm going to explain why not—and why, as you may already know from other sources, I expect many people alive today to live to 1000 years of age and to avoid age-related health problems even at that age.

I'll start by describing why it's unrealistic to expect these therapies to be perfect.
