Bryan Johnson, a biohacker known for his self-experimentation, announced a diagnosis of an incurable autoimmune disease lately. Doctors said the condition is difficult to diagnose and appears linked with low iron levels. Johnson noted the discovery does not alter his longevity work but introduces a personal health struggle.
The announcement lies after ongoing public updates on his brain-computer interface research. Observers point out how even well-funded self-experiments can encounter hidden medical threats. Johnson plans to continue sharing data from his current studies.
