Since the dawn of time, humans have been obsessed with the promise of eternal life - and we've done everything imaginable to find it: from bathing in the blood of virgins and injecting ourselves with strange serums, to freezing our brains and bodies in the hope of some future miracle.
But now a generation of scientists is trying to claim the field of gerontology back from the fringes. Armed with vast studies of "super-agers" and huge volumes of genetic data, these researchers are cutting through the contradictory messages about human aging and pinning down the unique elements that make some people live far longer than others.
In a fascinating article that grapples with the tidal wave of confusing age research we see each day, award-winning science writer Megan Scudellari goes inside the race to build drugs that stave off old age - and uncovers the deep-seated fears that drive its pioneers on.
