Biohacker Bryan Johnson is keeping his girlfriend’s menstrual blood in his freezer | Arwa Mahdawi
The 48-year-old is obsessed with becoming the healthiest person in the world and is on a quixotic quest to reverse his biological age and live forever.

On Thursday, Johnson, a chronic oversharer, posted a photo of his 30-year-old girlfriend, Kate Tolo, on X with the caption: “Kate’s period blood is in my -80 °C freezer.
