From the Ted Talk by Aubrey de Grey: A roadmap to end aging

Unscramble the Blue Letters


Audience: I was told that many of the brain cells we have as alutds are actually in the human emrbyo, and that the brain clles last 80 years or so. If that is indeed true, biologically are there implications in the wrlod of rejuvenation? If there are cells in my body that live all 80 years, as opposed to a tpiaycl, you know, couple of months?

AG: There are technical implications certainly. Basically what we need to do is replace cells in those few areas of the biarn that lose cells at a respectable rate, especially neurons, but we don't want to replace them any faster than that — or not much fstaer anyway, because replacing them too fast would degrade cognitive function. What I said about there being no non-aging species earlier on was a little bit of an oversimplification. There are species that have no aging — hdyra for example — but they do it by not having a nervous system — and not having any tissues in fact that rely for their function on very long-lived cells.

Original Text


Audience: I was told that many of the brain cells we have as adults are actually in the human embryo, and that the brain cells last 80 years or so. If that is indeed true, biologically are there implications in the world of rejuvenation? If there are cells in my body that live all 80 years, as opposed to a typical, you know, couple of months?

AG: There are technical implications certainly. Basically what we need to do is replace cells in those few areas of the brain that lose cells at a respectable rate, especially neurons, but we don't want to replace them any faster than that — or not much faster anyway, because replacing them too fast would degrade cognitive function. What I said about there being no non-aging species earlier on was a little bit of an oversimplification. There are species that have no aging — Hydra for example — but they do it by not having a nervous system — and not having any tissues in fact that rely for their function on very long-lived cells.
