The Public Cannot Distinguish Between Scientific versus Unscientific, Likely Good versus Likely Bad Approaches to Longevity

One of the challenges inherent in patient advocacy for greater human longevity, for more research into aging and rejuvenation, is that journalists and the public at large either cannot or will not put in the effort needed to distinguish between: (a) scientific, plausible, and likely useful projects, those with a good expectation of addressing aging to a meaningful degree; (b) scientific, plausible, and likely unhelpful projects, those that will do little to move the needle on life expectancy, and (c) products and programs that consist of marketing, lies, and little else. This last category is depressingly large, and the first category still depressingly small. There are examples of useful, high-expectation scientific projects in the senolytics industry, working on the means of removing senescent cells from old tissues. In animal models this is far and away the most impressive approach to rejuvenation attempted to date, applicable to many age-related diseases. The first good senolytic therapy will be revolutionary for human health in later life. As a counterpoint, an example of a poor and unhelpful scientific project is the use of metformin as a geroprotective drug, an approach that appears to very modestly and unreliably slow the progression of aging. Beneficial effects in animal studies are haphazard and small. The single study in diabetic humans shows only a small effect size. If devoting vast expense to clinical trials that target the mechanisms of aging, then why d...
