Technology Millionaire Resorts to Blood Transfusions from Teenage Son in Quest for Eternal Youth

Bryan Johnson spent $2 million a year on a team of doctors to make his organs function like a young person's.
Johnson received blood plasma from his 17-year-old son Talmage and gave blood to his 70-year-old father in an intergenerational blood swap.
Johnson follows a strict diet, exercise regimen, and frequent medical exams in an attempt to biologically reverse his age.
The procedure is scientifically questionable and potentially dangerous according to experts.
Johnson's motivation appears to stem from an anxiety over aging and mortality.
