Blood Boy for All – Young blood is a human right

Bryan Johnson’s Project Blueprint involves transfusing his teenage son’s plasma into himself, claiming young blood can reverse aging—a concept derived from heterochronic parabiosis studies that showed muscle regeneration, neurogenesis, and reduced inflammation in mice. Human trials have demonstrated safety and modest molecular changes linked to aging, but no clear efficacy, while Johnson’s costly at-home testing and commercialization efforts are criticized as impractical and inequitable.
