On April 13th, it was revealed that billionaire John Johnson recently shared photos showcasing the changes in his facial appearance since participating in anti-aging experiments since 2021, humorously noting even his Face ID seemed perplexed.
Simultaneously, he initiated an unconventional poll in the comments section, inviting netizens to judge his peak attractiveness.
In April 2023, Johnson underwent a unique plasma exchange therapy with his 17-year-old son, Talmadge, and his 70-year-old father, Richard.
During the process, medical personnel separated Talmadge's blood, extracting a transparent, pale yellow plasma, which was then transfused into Johnson's body.
Subsequently, Johnson also drew some of his own blood, which underwent the same procedure before being transfused into his father Richard's body.
On July 27th, 2023, a study published in the journal "Nature Aging" detailed a mouse experiment conducted by researchers from Duke University, Harvard Medical School, and anti-aging research company Altos Labs.
In the experiment, 4-month-old mice were connected to 2-year-old mice for 12 weeks of heterochronic parabiosis.
Upon disconnection, the physiological functions of the older mice improved, lifespan increased by 10%, and the epigenetic age of their blood and liver significantly decreased.
Commenting on this, Dr. Kang Zhijie, Chief Physician of Hematology at the Second Affiliated Hospital of Dalian Medical University, stated in an interview that there is currently no authoritative evidence to suggest that replacing young people's plasma helps maintain youth or slows aging.
Doctors Liu Qi and Zhang Bin from the Transfusion Department of the First Affiliated Hospital of the Army Medical University pointed out that plasma exchange is more commonly used in the treatment of autoimmune diseases and carries certain risks. For the general public, engaging in risky behavior for the sake of anti-aging warrants reconsideration.
Overall, plasma exchange remains a therapeutic technique. For health purposes, especially in the case of anti-aging applications not yet definitively validated, plasma exchange should be approached with extreme caution.
