A well-known bio-hacker was able to rejuvenate his heart by 5, and his lungs by 27 years.

Brian Johnson, a 45-year-old entrepreneur from the United States, experienced an experimental body rejuvenation program. After completing the Project Blueprint program and spending $2 million, he was able to achieve tangible results: judging by the tests, his heart became 5 years younger, his skin was like that of a 28-year-old, and his lungs were like those of an 18-year-old. The same - as a teenager, according to him, and nocturnal erections. It is not yet clear whether this is an advertisement for the company, however, scientists have been approaching this problem for a long time and the appearance of such rejuvenation has long been suggested.
