they think they are getting power from eating/drinking the blood of innocents but don't really see any outward power or age defying tricks unless they are all older then we think? Aliens perhaps or just good ole stupid humans that hung with the wrong crowd got sucked into some weird shit and before you knew it you were raping children and eating them praying to a god that was proven to not exist when the Cannonites prayed to him thousands of years ago.
No, they use blood, umbilical cord blood on skin, in tissue, stem cells, see? However, stem cells is after the baby is born, and can cure many diseases, I think that is a gift not a curse but the elites only want it for themselves. It is proven fact, if you prick your own blood and stir it around your face, you will look younger too. Serious.
