It seems that there’s something in the blood, so perhaps the vampires were onto something:
In his lab at UCSF and his postdoc lab at Stanford, Villeda and colleagues injected old mice with blood plasma from young mice, and vice versa. They found that the senescent rodents learned quicker and grew more neurons after infusions from young blood, while the juvenile mice got correspondingly worse at learning new tricks.
Muscle strength and blood flow also improve, but kids can rest easy because us old farts don’t need to suck all of the blood out of them; it looks as though the effects are attributable to just one little component:
the protein GDF11, the subject of two recent Harvard studies, which is also present in humans – has the capability to reverse many of the effects of ageing.
Even better, it’s readily sythesized, much like insulin, HGH, and other now-common and widely available medications. Of course, unlike Dracula, you won’t live for centuries with this stuff, but your quality of life should greatly improve. And you won’t have to avoid mirrors.
