Poor posture, particularly looking down or slouching, can restrict blood flow to the brain and harm its health, an issue that can be corrected through postural and movement habits.

The specific case of Bryan Johnson is based on an individual anatomical discovery (stenosis of the internal jugular veins) that his posture exacerbated. While generalizing this direct threat of 'killing one's brain' to the entire population is scientifically exaggerated, the literature establishes real links between posture and neurological health. Observational studies show a correlation between forward head posture and cognitive decline in the elderly, often linked to a reduction in proprioception or nervous system activity. There is also evidence suggesting that an upright posture can promote better stress (cortisol) regulation and cognitive performance in certain tasks. However, the idea that a standard office posture mechanically blocks cerebral circulation in a healthy person is not supported by robust clinical evidence. In summary, posture is a lever for neurological well-being, but the alarmist discourse regarding the immediate risk of brain damage is an extreme personal interpretation.
