Correction. They walk into a \u201cDon\u2019t Die\u201d dinner promptly at 5:00 p.m. for a night of futuristic conversation hosted by Bryan Johnson<\/a>, the famous longevity enthusiast spending millions a year\u00a0to reverse his age<\/a>. Guests enjoyed a meal of broccoli, cauliflower, black lentils<\/a>, and nutty pudding\u2014a concoction including walnuts, macadamia nuts, pomegranate juice, berries, and cinnamon. And in true Johnson fashion\u2014because sleep<\/a> needs to be optimized, too\u2014the dinner wrapped up at 7:30 that evening.\u00a0\u00a0<\/p>\n Johnson, who says he\u2019s aging at a rate of 0.64 years for every chronological year and celebrates his birthday every 19 months, shared Instagram<\/a> and TikTok videos from the gathering. Members of the Kardashian <\/a>family, including Khlo\u00e9, Kim, and Kris, sat alongside Johnson, plastic surgeon Dr. Jason Diamond, and podcast host Andrew Huberman<\/a>. The group enjoyed a meal together, followed by a photoshoot.\u00a0<\/p>\n Many were confused by this guest list and flocked to comment: It was \u201cthe collab nobody asked for<\/a>\u201d and looked like an \u201cAI-generated evening,\u201d according to two commenters. Another asked, \u201cWhere is my invite, Bryan?\u201d\u00a0<\/p>\n How did Johnson assemble such an eclectic group of high-profile people? \u201cThey organically form among friends of friends,\u201d Johnson tells Fortune. <\/em>He also notes that he cannot discuss what anyone said during the dinner in order to maintain their privacy.\u00a0<\/p>\n Johnson has hosted biweekly \u201cDon\u2019t Die\u201d dinners for the last few years, and has welcomed hundreds of guests\u2014including politicians, astronauts, artists, and scientists, he says. Johnson says the impetus for the dinners is to provoke conversations about what it means to be human. \u201cDon\u2019t Die\u201d is \u201cthe punchline of the dinner,\u201d he says.\u00a0<\/p>\n He tries to embody the phrase everyday by doing everything he can to optimize his health.<\/p>\n \u201cFor me to even begin to imagine that I get to predict my life expectancy would be insane. We can\u2019t see past a year, two, or three years,\u201d he says. \u201cThe only thing I do know is we need to build systems that don\u2019t die as a society.\u201d\u00a0<\/p>\n The food served at the dinner is what Johnson eats daily, which is designed by his team of doctors who help curate his Blueprint\u2014a specific lifestyle plan and regimen for exercise, supplements, and more.\u00a0<\/p>\n Johnson says he begins every \u2018Don\u2019t Die\u2019 dinner with two questions.\u00a0<\/p>\n \u201cI say, if you had access to an algorithm that can give you the best physical, mental, and spiritual health of your life, but in exchange for access to the algorithm, you would have\u00a0to go to bed when it said, and you would exercise in the way it said, would you say yes or would you say no?\u201d\u00a0<\/p>\n Next, he asks people to think about the 25th century and how future people will think about the morals, ethics, and norms of today. \u201cThe next question invites introspection and contemplation of who we are in this moment,\u201d he says.\u00a0<\/p>\n The Kardashian family, known for their beauty brands, have been eager adopters of new technology aimed at keeping their insides as healthy as their exteriors. They\u2019re part of the trend of wealthy longevity enthusiasts who are buying and promoting subscriptions and tests that claim to indicate how well you are aging or promise longer lifespans. Kim Kardashian was among the first supporters of Prenuvo\u2019s full-body MRI scan<\/a>, which aims to spot early signs of disease, sharing the experience with her over 360 million Instagram followers.\u00a0<\/p>\n While a dinner over nutty pudding and longevity-themed conversation is harmless, critics have posed concerns about Johnson\u2019s methods and about the emerging field of longevity science.\u00a0<\/p>\n Whole-body MRI\u2019s, for example, are not recommended by the American Academy of Radiology<\/a> for preventative purposes as there is insufficient evidence to back up their efficacy. The longevity science field is also fairly new, and experts have cautioned that some longevity science is just pseudoscience.<\/p>\n Johnson has come under fire for experimenting with approaches not FDA approved like swapping blood with his teenage son<\/a>. Still, he is all in on the mindset of biohacking his way to a longer life and says he does not promote his $333-a-month Blueprint protocol<\/a> at the dinners (although anyone is welcome to sign up).\u00a0<\/p>\n \u201c\u2018Don\u2019t Die\u2019 is the most commonly played game by every human on the planet,\u201d Johnson says. \u201cAs a species, we love games. I think \u2018Don\u2019t Die\u2019 could basically be the next game we play.\u201d\u00a0<\/p>\n<\/div>\n
