What's more, it seems that it is possible to reset the epigenetic of cells to their youthful state and reverse actual the biological age of those cells. They don't just "measure younger", they function as they did when they were younger.

- perl4ever 5y ago>currently the most accurate way to measure aging I don't understand what people mean by statements like this. Per the Wiki page, they found something that on average is highly correlated to chronological age. But in individual cases, it may be off a little or a lot. What tells you this is meaningful information and not random noise? What is the reference point for the "real" age that is not chronological age?

- perl4ever 5y agoIt appears to me to be "more accurate" because they have defined the discrepancies as more accurate. Why not just define them as inaccuracy?

- jaygernaught 5y agointeresting, what are your thoughts on modifying our epigenetics via crisper to pulse Yamanaka factors? also what ever happened to that CEO who gave her immune system a boost with stem cells?
