Bryan Johnson's latest MRI scan dropped some wild biometrics:
Subcutaneous + visceral fat levels: biological age equivalent to someone in their 20s
Cardiac health: 100% score, again tracking to 20s range
Hippocampal volume: 99th percentile (brain structure associated with memory and spatial navigation)
Radiologist's assessment: "indistinguishable from an elite athlete"
This is coming from someone running an extreme longevity protocol with strict diet control, supplement stacks, and constant biomarker tracking. The hippocampal data is particularly interesting since that region typically shrinks with age - staying in the 99th percentile suggests his neuroplasticity interventions might actually be working at a structural level.
Whether you buy into his full Blueprint protocol or not, these are objectively impressive metrics for someone in their mid-40s. The visceral fat numbers especially matter because that's the metabolically active fat linked to insulin resistance and cardiovascular risk.
