I did a post about it about a year ago. Peter Thiel the founder of E-Bay is into getting transfusions of youthful blood... This goes all the way back to Elizabeth Bathory who used to drink blood- there was a rumor that she bathed in it, but totally unsubstantiated. In fact the blood drinking may have been fabricated by wealthy nobles wanting her property (which was considerable) However, it must have gone on somewhere, or otherwise how would they know about it.

There were also allegations about Hillary practicing it- given the sudden changes in appearance- who knows? There are academic "studies" extolling the youthful properties of juvenile blood... Watch your kids... come to think of it- you're in the UK... the same things are being said about you know who QE II
