00:00We know that we can target the process of aging, delay it significantly, even stop and reverse it in some context.
00:09And we've done it in animals, and we've done it in humans.
00:14Now to your question, you know, what is this biology?
00:18And I'll tell you really simply, we geroscientists agree on a concept that's called the hallmarks of aging.
00:26What are the hallmarks of aging?
00:28Something that goes wrong when you're old, and when you fix it, you can fix it in animal with genetic ways, or with drugs, or in humans also.
00:39You target this hallmark, you reverse the aging, you extend the health span of the animals and humans, and you increase their lifespan.
00:50That's how you become a hallmark.
00:52Now, there may be 12 hallmarks like that, but the important thing is, you fix one, you can fix the others.
01:00Most of the drugs that we're doing are doing that.
01:04So you don't have to fix all of them at one time to get an effect.
01:09Maybe it's going to be better if you do that.
01:11But we have a biology, we have targets, and we can start dealing with it right now.
01:18We have targets, because we're not going to be able to fix all of them.
01:31We don't have to suffice it.
01:32We don't have to be fascinated by the biology of the animals.
01:36But we don't have to be able to fix all of them.
01:39You don't have to be able to fix them in this way.
