The tech entrepreneur Bryan Johnson, who has built a public brand around trying to slow his own ageing, says he completed 60 hyperbaric oxygen sessions in 90 days and published the biomarkers he claims improved, from inflammation to telomere length. Whether the numbers hold or not, the notable part is the format: one person running his body as an open, documented experiment and turning the protocol into content.
It shows how far self-optimisation has travelled from the clinic. Treatments once reserved for wound healing or diving medicine are reframed as consumer anti-ageing tools, with an audience following along. The claims remain unproven and hyperbaric therapy carries real risks; the sign is less the oxygen itself than the spread of a ‘measure everything, optimise everything’ mindset.
So…:
Self-optimisation becomes content. Where is the line between inspiring people and turning yourself — or others — into test subjects?
