Bryan Johnson, a biohacker known for his anti-aging work, announced a diagnosis of an incurable autoimmune disease this month. Doctors said the condition is elusive to pin down and is associated with low iron levels. Johnson noted the discovery has not changed his longevity work but introduces a personal health struggle.
The announcement lies after ongoing public updates on his metabolic upgrade studies. Experts note how even high-budget self-experiments can encounter hidden medical risks. Johnson intends to continue sharing data from his active studies.
