What if we didn't have to worry that the clock was ticking? And what if I told you that soon — very soon, in fact — we won't? - David A. Sinclair

I believe that aging is a disease. I believe it is treatable. I believe we can treat it within our lifetimes. And in doing so, I believe, everything we know about human health will be fundamentally changed.

Our equivalent of the Lord's Prayer was the English author Alan Alexander Milne's poem "Now We Are Six," which ends: But now I am six, I'm as clever as clever. So I think I'll be six now for ever and ever.

If you've had your genome analyzed, you can check if you have any of the known variations of FOXO3 that are associated with a long life.40 For example, having a C instead of a T variant at position rs2764264 is associated with longer life. Two of our children, Alex and Natalie, inherited two Cs at this position, one from Sandra and one from me, so all other genes being equal, and as long as they don't live terribly negative lifestyles, they should have greater odds of reaching age 95 than I do, with my one C and one T, and substantially greater than someone with two Ts.
