I wrote a post a while back in which I traced a brief history of using children's blood in an effort to stay young. This sick undertaking is predicated on the belief that doing so prolongs life and I believe that it's what the "killing room" at Ping Pong Pizza is being used for. Apparently, I'm not the only one. This video shows a blog from Voat (I'm not familiar with it) citing this practice as "science." Here's the video, you can make your own minds up...looks fairly conclusive to me.
