Successful ageing, in medicine, is a perfectly respectable concept – and anti-ageing less so. But the two fields share precisely the same aims: an old age of healthy vigour, free from disease, engaged in one’s communities”. So argues Martha Gill in The Observer, musing on reactions to Martha Stewart’s Sports Illustrated appearance (see post below). She points to a conflict in the scientific world, centring on a new generation of anti-ageing drugs that kill or supress senescent cells, an advance “partly outside mainstream gerontology and vaguely associated with quacks and deluded billionaires”. But senescent cells can trigger Alzheimer’s, heart disease and osteoporosis and it makes sense, she says, to think of age as a disease to be fought.
