We will do some crazy things to look and feel young. The latest bonkers trend is apparently replacing your blood supply with the blood of the young, vampire-style, for a mere £6,500.

Ambrosia, founded by entrepreneur Jesse Karamazin, is conducting a trial to study the effects of receiving blood and plasma from teens and young adults. The idea was inspired by studies on mice who had their veins conjoined that showed some effects of aging were reversed or accelerated when older mice received blood from young mice.

However, many say the study is poorly-designed and not scientific. Also, they claim there are ethics violations in running a study that requires participants to pay and that will generate up to £4 million in revenue for Ambrosia.

Furthermore, it is unclear if a one-time human blood transfusion could yield similar results to studies in mice where the mice shared blood for almost four weeks.

"People want to believe that young blood restores youth, even though we don't have evidence that it works in humans and we don't understand the mechanism of how mice look younger," Stanford University neuroscientist Tony Wyss-Coray told MIT Tech Review. "I think people are just attracted to it because of vampire stories."
