To find out more, I drove to the Buck Institute for Research on Aging which is based in the beautiful city of Novato, near California's wine country. It's the kind of place that would make you want to live as long as possible.

Here I met Dr Eric Verdin, one of the world's foremost experts on the science of ageing.

He was less persuaded by Alkahest's claims of using young blood to rejuvenate the old.
