"I see you didn't make it to the bottom of that article that says there's no proof blood transfusions reverse aging."
I see you continue to put words in my mouth. I say 'retard aging' and you insert 'reverse aging'. These are not at all the same thing. The blood factors from kids transfused into old people definitely supply those factors that have degraded physical condition of the aged due to their lack. That isn't in any way rejuvenating or restoring youth to the aged, but is simply retarding that degradation caused by lack of those factors due to aging.
These technologies need to be tested before the people that can afford them will buy them. Scamming is what 'Jews' do. They've always done so, and will always do so as long as they exist, so doing so now is nothing new.
