If you had the money what would you do to stay forever young ? According FORTUNE, tech billionaire Bryan Johnson recently recruited his 17-year-old son, Talmage, and his 70-year-old father, Richard, to join him in “the world’s first multigenerational plasma exchange.”
The procedure took place at the Resurgence Wellness, a medical spa in Texas where Bloomberg reports the youngest Johnson got a full liter of his blood removed (for context, the human body has about five liters of blood) and separated into a batch of liquid plasma and then a batch of red blood cells, white blood cells, and platelets.
Next, Bryan himself underwent the same process with the addition of having the same quantity of his son’s plasma infused into his veins. Finally, the multimillionaire’s father had some of his own blood drained to make room for Bryan’s blood.
