American millionaire uses 17-year-old son's blood to rejuvenate

American millionaire Bryan Johnson transfused plasma from his 17-year-old son's blood to fulfill his dream of reversing his biological age .

According to Bloomberg , tech entrepreneur Bryan Johnson , 45 , recently went to a health clinic in the Dallas, Texas, area with his 17-year-old son Talmage and 70-year-old father Richard to participate in an intergenerational blood swap treatment , in which older adults receive plasma from their children.

A liter of Talmage's blood was then drawn out of his body and placed in a machine to separate it into liquid plasma, red blood cells, white blood cells and platelets. The plasma was then infused back into Bryan Johnson's vein. The process was then repeated with Richard.

This is not the first time millionaire Johnson has visited a clinic to receive blood from someone younger than him. In previous visits, he received blood from an anonymous donor who was carefully selected based on his body mass index, blood type, diet and overall health profile.

This isn't Johnson's first foray into rejuvenation. Earlier this year, Bloomberg reported that the tech founder is looking to restore his 'brain, heart, lungs, liver, kidneys, tendons, teeth, skin, hair, bladder, penis, and rectum' to the state they were when he was 18. The effort is costing Johnson about $2 million a year, as he hires a team of 30 doctors and specialists to advise him on how to regain his peak teenage physique.

Bryan Johnson is not alone in the world of wealthy people trying to regain their youth. In essence, people like Johnson are extracting the blood of young people to gain the age-reversing properties it supposedly provides.

Ever since the days of Countess Elizabeth Báthory, who drank and bathed in virgin blood to stay young, the concept has been a regular fixture in folklore. Now, some researchers are starting to suggest that there may be a scientific basis for all this youthful blood business.

Some studies in mice have shown that when these rodents are grafted together to share a circulatory system, the older animals appear to have some cognitive and circulatory improvements. However, it is unclear whether those findings would have the same effect on humans.

Amid concerns about a scenario similar to the "blood boy" phenomenon depicted on HBO's "Silicon Valley ," the Food and Drug Administration issued a warning in 2019 against the practice of young people's blood transfusions, calling the therapy " unproven."

"There is no clinically proven benefit of plasma transfusions from young donors to cure, mitigate, treat, or prevent disease. Additionally, there are risks associated with the use of any plasma product ," the FDA has warned.

Experts have expressed some serious doubts about the practice of blood injections or plasma transfusions, fearing it could be harmful to health.

'To me, this approach is disgusting, unproven, and quite dangerous,' Charles Brenner, a biochemist at City of Hope National Medical Center in Los Angeles, told Bloomberg.

Brenner has an interesting theory about why people would want to swap blood with their immediate relatives . 'People who come into these clinics and want anti-aging infusions basically have anxiety issues. They're worried about their own mortality ,' he says.

However, Johnson countered: " We start from the evidence, not from emotions . "
