The thing is about health, about aging is that I realize Yeah. You're 25 years old and we have this really good system in capitalism where you have a certain amount of money in your bank account and when you spend money it lowers your bank account. You're like, "Oh, spending money lowers bank account or making money increases bank account." But we don't have the same kind of accounting system for age. And so we basically like we look at ourselves in the mirror every day and we're like, "Yeah, about the same." Or like I kind of feel the same. And so we don't understand at a molecular level what's happening inside. So there's no accounting. So people spend down their life just like they spend down a bank account and they don't realize they're spending it down. And so that's what measurement does. It's basically like a bank account where you see either the numbers are you increasing in wealth or decreasing in wealth.
