Anti-ageing medicine may not be the most well developed branch of healthcare and medical research, but one thing it doesn’t lack is self confidence. “Anti-aging medicine is the pinnacle of biotechnology joined with advanced clinical preventive medicine,” according to the website of the American Academy of Anti-Aging Medicine (A4M), one of the leading organisations in this endeavour.1 “It is scientific . . . It is evidence-based . . . It is well-documented in peer-reviewed journals.” The advances on offer to patients are the “most potent emerging biomedical technologies today.”
Some manifesto. And while A4M members and most other anti-ageists limit their ambitions to minimising age related disease and achieving a modest increase in longevity, a minority of true believers foresee much more: the indefinite postponement of death. Orthodox science may be irritated by what can be seen as ill founded over-optimism, but the notion of fending off the decrepitude of old age has always captured the public imagination. By 2015, according to one estimate, the global market in anti-ageing products will be worth nearly $300bn (£190bn; €210bn) annually.2
What, precisely, is encompassed by the term “anti-ageing”? A great deal of ordinary everyday medicine, be it the prevention of strokes or the removal of malignant tumours, is about prolonging life. But the full bloodied anti-ageing prospectus goes beyond this; it focuses not only on the diseases associated with age but on the process of ageing. Evidence of the benefits of disease interventions is overwhelming; those aimed at the ageing process are still characterised less by achievement than by theory, by extrapolation from laboratory experiments, and by a limited amount of animal work. The gulf separating the two remains wide if not unbridgeable.
You don’t of course …
