But yeah. Anyway, so like back to the biomarkers, this is what we were trying to do is like we are trying to follow data everywhere. And over the course of doing this, uh I became I think the most measured person in human history. There's no human ever to exist that has more biological age measurements done than me. And that data gave this like treasure trove of of insight of like what to do and how to do it. And then we started working with the science to say how do we now optimize these markers? And so a lot of people in the beginning were so confused by what we were up to. They're like, "What is this guy even doing? This is so weird. Like I don't understand it." And we're like, "Actually, we're measuring biological age because like intuitively if you take an a 90-year-old and a 2-year-old and you put them adjacent to each other, you know which one's 90 and which one's two. There's no confusion. If you put a 35 and a 34 year old next to each other, it's not clear who's who. Like that's that's based on eyesight. Yeah. Based on eyesight. Exactly. Uh so what I'm saying that intuitively you understand that organs have a structural and a functional element of biological age. You can actually look at a heart and say based upon its function and based upon its cellular structure you know fun cellular anatomical um reading what is the biological age and so yeah we did this over the entire body. And so yeah uh last month we posted 60 plus uh of my biomarkers. Now we have many many more but we chose these 60 because they rank among the highest as being predictive for all cause mortality and uh we made the case that I have the best biomarkers of anybody in the world not just a 47y old but literally better than anybody in the world and um you know like I haven't known exactly how to think about that like how accurate is that is it the case that if you actually were to sample everybody that by default you'd find people with better markers. I'm honestly not convinced like I legitimately think it it could be the case that out of 8 billion people I have the best comprehensive biomarkers in the world at age 47. I think it really is a possible and that but the the point is here is not to be number one. The point here is to say we have created like rankings in society to
