Bryan Johnson, the life extension guru who chronicles his efforts to reduce his \u201cbiological age,\u201d says he has Autoimmune Gastritis<\/a> (AIG), an incurable disease that he only discovered he had in May. Johnson wrote on X that he doesn\u2019t know how long he\u2019s actually had AIG, which causes B12 and iron deficiency, leading to anemia. But he\u2019s vowing to work on \u201cexperimental approaches\u201d to find a cure and has asked anyone working on the disease to reach out.<\/p>\n

Johnson, who\u2019s 48 years old and constantly chronicling his efforts to maximize his health online, blamed his AIG on unhealthy foods he ate in his youth, along with the stress that came with being a father.<\/p>\n

\u201cAs a kid, I ate sugar cereal, drank sugary soda, and gobbled down fast food. I had a few healthy years in my early 20s but then became a young father of three and began building a business,\u201d wrote Johnson.<\/p>\n

\u201cJuggling that stress and grind, I let my health slip and gained 40 lbs. Within a few years I\u2019d fallen into a deep, chronic depression. Somewhere in that timeline, my body began developing an autoimmune process affecting my thyroid and then my stomach lining,\u201d Johnson continued.<\/p>\n

Bad news #1: <\/p>\n

I have an autoimmune disease. My stomach is eating itself.<\/p>\n

Bad news #2: <\/p>\n

2\u20135% of people have this, too. Likely more, because it hides.<\/p>\n

Good news: <\/p>\n

I’m going to try and solve it. Will share all.<\/p>\n

Johnson takes dozens of pills per day<\/a> and was featured in a 2024 Netflix documentary called Don\u2019t Die: The Man Who Wants to Live Forever. He founded the company Braintree, which bought the payments app Venmo in 2012. Johnson then sold Braintree to PayPal for $800 million.<\/p>\n

Johnson owns a company called Blueprint that sells a number of products<\/a> he says can make you live longer, including everything from dietary supplements to extra virgin olive oil. He\u2019s spent millions in an effort to live forever and his obsession is often criticized as no way to live a life of fulfillment and joy. But the tech founder rejects those criticisms and seems to believe that his new diagnosis has completely validated his worldview.<\/p>\n

\u201cIt\u2019s worth noting that many of you give me a hard time, inviting me to \u2018live life\u2019 and engage in self-destructive behaviors like a \u2018normal person\u2019. I\u2019m cool with the playful ribbing. Also, had I not taken care of my health during the past five years, my situation could potentially be very serious,\u201d wrote Johnson.<\/p>\n

The playful ribbing takes many forms online, but some of the most ridiculed tweets Johnson has posted involve things like tracking his 19-year-old son\u2019s erections in order to compare them to his own. He also chose to tweet about his son\u2019s erections in a rather odd manner, writing \u201craise children to stand tall, be firm, and be upright.\u201d<\/p>\n

Johnson has also spent millions on blood transfusions from his son, something that has connections to bad illnesses<\/a> like graft-versus-host disease, according to the NIH<\/a>. He\u2019s also tracking the amount of microplastics in his semen<\/a>, the kind of analysis that most normal people would not necessarily become fixated on.<\/p>\n

But this is no normal man. Johnson is determined to age in reverse, and will do just about anything to make that happen, even if it\u2019s not technically possible. He\u2019s also an optimist in many ways, as you can see in his tweet about the diagnosis. He firmly believes that anything is possible if you throw enough technology at a problem. Even conquering death.<\/p>\n

\u201cIn the age of AI, multiomics, and custom-built DNA, proteins, and cells, no condition should be presumed incurable simply because no one has yet tried to cure it with today\u2019s stack,\u201d wrote Johnson.<\/p>\n

Johnson\u2019s company Blueprint didn\u2019t immediately respond to questions emailed Monday. Gizmodo will update this article if we hear back.<\/p>\n
