Bryan Johnson, the multi-millionaire biohacker famed for his extreme anti-aging regimen, has once again captured public attention, but this time for reasons far removed from his quest for immortality. The 48-year-old, who recently predicted achieving immortality by 2039, is facing a wave of online criticism after sharing intensely intimate and clinical details of a reunion with his new girlfriend, Kate Tolo.
The 'Weird' 850-Word Tweet That Broke The Internet
Known for documenting almost every facet of his life online, Johnson took his sharing to a new level on the platform X. After being apart from his girlfriend for nearly 20 days, he penned an exhaustive 850-word post describing their meeting in minute, biological detail. The tweet, posted in early December 2025, began by noting the exact duration of their separation: 19 days and 20 hours.
He described Kate's need to shower after travel as a ritual to "cleanse herself of a dirtied world." However, it was the subsequent description of their physical affection that left netizens bewildered. Johnson wrote about feeling goosebumps on her body and then launched into a scientific explanation, stating, "Her hypothalamus stimulates the release of GnRH, which tells the pituitary gland to wake up her reproductive system." He further added that their "olfactory systems consume each other with delight, signalling immune system compatibility."
Netizens React: From '50 Shades of Grey Matter' to Freezer Jokes
The online reaction was swift and overwhelmingly mocking. Users on X were quick to call out the post's absurdity and oversharing nature. One popular comment compared the writing style to "50 Shades of Grey Matter," cleverly blending the title of the famous erotic novel with 'grey matter,' a term for the brain.
Others made darkly humorous predictions. "This is the kind of tweet that gets read aloud in a court room months after they find someone in a freezer," one user quipped. Several comments pointed out the genre of the post, labeling it "science erotica" and asking, "What in the erotica is going on here?"
Many expressed sympathy for Kate Tolo, with one netizen stating, "can't imagine Kate not getting the ick after reading this." Another referenced Johnson's immortality goals, joking, "Once again, all it took to lose immortality was just Eve," drawing a biblical parallel.
A Pattern of Public Sharing
This incident is not an isolated one for Bryan Johnson. The longevity expert, who spends a significant portion of his fortune on his age-reversal experiment, has made a habit of publicizing his private life. He had previously introduced Kate Tolo to his followers on Instagram in early December 2025, expressing profound joy, writing, "I’ve wanted this my entire life and impatiently waited 25 years for it to arrive. It’s better than anything I imagined."
While his scientific approach to health and longevity has garnered both intrigue and skepticism, this foray into documenting his romance in such a detailed manner seems to have crossed a line for the public. The backlash highlights a clear boundary that even followers interested in biohacking are not willing to cross, marking a rare moment of unanimous critique for the controversial figure. The episode serves as a reminder that some aspects of life, perhaps, are better left offline.
