It appears not, we have the studies that show training can reverse those epigenetic clocks, via stress adaptation, and the studies that show exercise accelerates the rate of actual cellular aging. As you would put it, exercise trades fitness for what you are calling health. I know that wasn't your intention to have the field taken over by fitness buffs, but the flawed nature of the clocks appear to have enabled this. I don't think the name is a problem, the problem is what you measured. I don't consider a 60 y/o face, with 40 y/o muscles, after 50 birthdays health worth billions in investment. Slaves who worked fields were fit as fiddles, they were strong until they collapsed abruptly at the end of middle age. The case for the most minimal fitness intervention you can get away with appears to be aligned with maximum healthspan and lifepsan but not fitness.
