One of the better ways to dampen down the unhelpful hype generated by one or another new supplement or drug alleged to modestly slow aging on the basis of animal data is to point out that aspirin does just as good a job in animal studies. We all know what aspirin does for human life span, which is to say pretty much nothing, while still managing to be a useful tool in the pharmaceutical toolbox. Chasing marginal outcomes in human longevity will at best achieve marginal outcomes – and that is the major problem with the mainstream focus on trying to recapture the beneficial effects of calorie restriction through any number of candidate calorie restriction mimetic drugs. We need to do better, to aim higher. This means more work focused on the development of therapies after the SENS model, those that repair the molecular damage that causes aging and thus are capable in principle of achieving rejuvenation and significant extension of healthy human life.
