Tech millionaire Bryan Johnson is an entrepreneur, venture capitalist, and fitness and?bodybuilding enthusiast obsessed with anti-aging. Johnson became a millionaire after founding Braintree in 2007. The company’s web payment processing system was so effective that PayPal, which was under eBay in 2013, acquired it from Johnson in exchange for $800 million. However, the entrepreneur has shifted his focus from business to health and fitness.

In recent years, the 46-year-old has become obsessed with anti-aging. Besides going through a fitness transformation and changing his lifestyle, Johnson isn’t afraid to try unorthodox methods to look and feel younger. In April, Bryan Johnson became the first human to try an experimental procedure to fight aging. The procedure involved his 17-year-old son and 70-year-old father.

The first multigenerational plasma transfer

In May, Bryan Johnson posted on social media about doing something no one had attempted before. In his post, the then-45-year-old wrote about the experimental blood plasma exchange he underwent. The multi-millionaire uploaded an image of himself and his son, each holding a vial of their blood in their hands.

“My son, father, and I completed the world’s first multi-generational plasma exchange,”?Johnson wrote.?“Once divided by the mind, now united by biology,”?he added. So what was this multigenerational blood plasma exchange? Why did Johnson do it? The venture capitalist explained this in the YouTube video documenting the procedure.

In the video, the fitness enthusiast spoke about the first lab experiment that exchanged plasma between two mice. One mouse was older, while another was younger. After the plasma exchange, the older mouse started to reverse age. While there have been human trials of the lab test, Johnson, his 17-year-old son, and his father performed the first multi-generational exchange.

The procedure involved taking blood from each individual, separating the plasma, and then infusing the younger plasma into the older individual’s bloodstream. Johnson said there is an inherent risk involved, despite rigorous baseline testing. Thankfully, none of the three family members showed any side effects. However, transferring his son’s plasma into his body isn’t the only thing the anti-aging crusader?does to fight the symptoms of aging.

Fighting aging through fitness and diet

In June, the man who spends $2 million each year to look younger collaborated with fitness content creator Jesse James West. In their video, West visited Johnson’s place?to live like the Braintree founder. The video shows the daily routine of the millionaire, whose life goal is to fight and possibly reverse the effects of aging.

In the video, Johnson put West through the paces. The 23-year-old bodybuilder found it challenging to keep up with the 46-year-old. Besides working out, Johnson also showed his vegan diet and the 60 different supplement pills he takes every day. However, West was even more surprised to find that Johnson regularly undergoes a plethora of medical tests to monitor his body.

There were no visible results of the multigenerational blood plasma transfer. However, Johnson has done it only once and hasn’t announced any plans to do it again.
