Bryan Johnson argues that looking young matters because it reflects actual health, not just vanity. He's pursuing biological rejuvenation to reach an 18-year-old's physiology without plastic surgery, treating appearance as a window into how your body actually works.
You also focus on, like, the aesthetic stuff, making sure your skin looks good. Is that something that, like, psychologically that helps you be healthier or does it actually make you be healthier? Both.
Let's imagine now that we have some indeterminate time which we can live, we will have the natural desires to look and feel our best. And that means we're going to want nice skin, we're going to want to have good muscle and physical abilities. We have done everything to try to basically get me equivalent to a biological 18 year old. I have not done plastic surgery surgery. I haven't done things that mask age. I've done things that try to legitimately rejuvenate to a younger biological state.
