Kate Tolo Tracks 1,500 Biomarkers for Endometriosis

Kate Tolo, 30, is tracking over 1,500 biomarkers across her menstrual cycle with $2.6 million from Immortals, the wellness company she founded with boyfriend Bryan Johnson. She claims noninvasive tests diagnosed endometriosis in 42 days, though she never had surgery or official diagnosis. Physicians question whether one person's results can apply to a general population.
