Bryan Johnson says he found his ‘Abigail Adams’ after decades of searching for love: ‘Single most anti-ageing move’

That shifted when he met Kate Tolo at Kernel, Johnson’s neurotech company. Tolo, whom he described as a “30-year-old Bosnian-Australian-American who once dreamed of a career in fashion,” was instantly drawn to his ideas about the future of humans and AI. Despite their vastly different backgrounds, Johnson wrote that they recognised an unusual energy in each other. “The puzzle piece fit was immediate, as immediate as either of us had ever experienced.”

Even with that spark, the two agreed early on to keep strict professional boundaries, shaped by past relationship experiences that made both cautious. Still, their nightly conversations in his office slowly became the highlight of his day. Johnson admitted that his emotions tugged at him even when logic told him to keep his distance. He called Kate “luminescent”, praising her love of thrifted fashion, her inventive eye, and her unpredictable way of thinking. “She was art,” he said.

Their bond deepened while working together on Project Blueprint, the anti-ageing regimen that later became Johnson’s worldwide protocol. For 18 months, they both tiptoed around their feelings—he out of fear and she due to growing up “to distrust all things”. Eventually, Johnson raised the question neither had dared to voice, and she acknowledged she felt the same.

Guys…I have a girlfriend.

Now I know what you’re thinking…how is it possible that anyone would want to be with me? I understand where you’re coming from. I think the answer is: her puzzle piece fits mine.

They chose to keep their relationship quiet for years, giving it time to develop away from the public gaze. Johnson admitted that bridging their different lives—he, a divorced father of three, and she, younger and from a different cultural background—required patience and slow adjustments. Over time, he said, their partnership found its rhythm: stable, calm, and deeply compatible.

In the post, Johnson praised Tolo not just as a partner but as a core part of the machinery behind his ventures, including Blueprint and Don’t Die. He highlighted her ability to analyse situations sharply and see emotional subtleties he might miss. “Relative to her, I feel myopic,” he wrote, adding that she brought “prescience and thoughtfulness” to every project. He pushed back against people who assumed she was merely an assistant, calling that perception a major misunderstanding of her contributions. “It’s such a loss because people are looking for what she has to offer,” he said.

Johnson also credited her with helping him mend his relationship with his father. His bond with Tolo and his son Talmage had grown into a close-knit trio, filled with conversations he described as “fast, dark, rowdy”, the kind that create comfort and trust. Talmage, he added, often used Kate as the benchmark when he thought about who might be a good partner for his dad.

Towards the end of his post, Johnson reached for an analogy drawn from the famed expedition of Ernest Shackleton, who survived 497 days adrift in the Antarctic after being shipwrecked. After years of searching for meaningful companionship, he wrote, finding Kate felt like reaching land after drifting for far too long: “Kate feels like land to me after being adrift and searching for 25 years.” He ended the message with a line that summed up the depth of his feelings: “Lucky me, I found my Abigail Adams.”

Alongside the post, Johnson shared a collage documenting moments from their relationship. The reaction online was overwhelmingly warm. One commenter wrote, “Congrats Bryan. Finding the right person is also a massive net positive for living longer.” Another teased him: “There goes any attempt at becoming younger… start documenting girlfriend stress to see if it affects your longevity lol.” A third wrote, “Find a partner that writes essays about you like Bryan writes about his girlfriend,” while another added, “This is the single most anti-ageing move in his entire protocol.”

Tolo, who frequently appears in Johnson’s videos about his lifestyle and has stood by him during everything from public talks to the livestream incident where he consumed psychedelic mushrooms, has long been a quiet but steady presence in his life. She even joined him earlier this year at Paris Hilton’s birthday celebration.

Now, after keeping their relationship private for years, Johnson’s post finally offers the public a glimpse of the partnership that has shaped so much of his life behind the scenes, one he clearly sees as his most meaningful discovery yet.
