Biohacker May Be Having Some Regrets

Bryan Johnson, the quirky tech multimillionaire who's turned his body into a longevity lab, is suddenly wondering if he overshot the mark. Per the New York Post, the 48-year-old biohacker, known for spending millions on anti-aging experiments and infamously using his teenage son's plasma in so-called "blood boy" transfusions, posted on X on Wednesday evening: "Been thinking things over and wonder if I've taken this whole longevity thing too far." The pause comes after Johnson revealed he's been diagnosed with autoimmune gastritis, a chronic condition that affects the stomach lining.

It also follows his recent claim that he'd "cloned" himself as a newborn to one day harvest organs—an announcement he acknowledged might sound like "a dystopian future." Johnson has poured roughly $10 million into tracking his body, testing supplements, and publicizing intimate info, from updates on sperm microplastics to his wife's reproductive health data, drawing both fascination and backlash. Whether his latest health news leads to a course correction, or just the next experiment, remains unclear.
