Harvard biologist David Sinclair is so convinced he has the secret to staying 'biologically young' that
he *ta da* sells it. And it is all things you can buy. Or do.
He is mostly vegetarian and mostly doesn't drink. Okay, a moderate diet and exercise, you don't need a degree for that, you just need to have read "Readers Digest" any time since 1963. He looks young and perhaps always will, but just like someone may buy some brand Kim Kardashian sells, it doesn't mean they will look like her, it is an aspirational purchase. He knows that but wants to sell you stuff anyway.
