Bryan Johnson invests $52 million to map girlfriend Kate Tolo’s body

Tech billionaire Bryan Johnson, known for spending millions on anti‑aging research, has launched a new project to map the body of his three‑year‑old girlfriend, Kate Tolo, an Australian co‑founder of the health company Blueprint. Johnson says the effort will cost about $2 million a year (roughly 52 billion VND) and involve more than 100 measurements each day for about 100 days, covering a full menstrual cycle.

The daily regime includes sleep‑ring tracking, saliva and cheek swabs, oral temperature, urine cortisol and hormone tests, pelvic‑floor strength, blood pressure, body imaging, grip strength, blood tests for aging rate, and sensory assessments for smell, taste, hearing and pain sensitivity. Tolo also performs gym sessions, skincare routines and takes supplements. Johnson aims to collect around 14 million data points from Tolo, compared with the 1.5 billion points he gathered from himself over five years, to create the most detailed physiological baseline for a woman in history.
