Tech billionaire swaps blood with son and father in anti-aging quest

Tech entrepreneur Bryan Johnson spent $2 million a year on anti-aging treatments, including blood transfusions from young donors. He recently underwent a multigenerational plasma exchange with his 17-year-old son and 70-year-old father at a medical spa in Texas. The FDA advises against infusing young blood for anti-aging purposes, but Johnson's medical team approved the procedure as a possible treatment for cognitive decline. Johnson claims to have the heart of a 37-year-old, the skin of a 28-year-old, and the lung capacity of an 18-year-old.
