Bryan Johnson ponders if he's 'taken this whole longevity thing too far' after diagnosis

Bryan Johnson, the tech entrepreneur-turned-longevity influencer, is now thinking about whether he has taken it too far when it comes to his "don't die" movement. The move comes after Johnson was diagnosed with an autoimmune disease earlier in 2026.  

"Been thinking things over and wonder if I’ve taken this whole longevity thing too far,” Johnson wrote on X. 

The post from Johnson comes just a few weeks after Johnson announced that he was diagnosed with Autoimmune Gastritis, an autoimmune disease that attacks the stomach. 

"My hypothyroidism got diagnosed when I was 21 years old with a routine blood draw. That enabled me to begin proactive management, supplementing levothyroxine and Armour Thyroid. They are the hormones my body should be producing on its own but wasn’t. By taking these pills daily, my body was able to operate as though my thyroid was functioning properly. What I didn’t know was that something else was going on inside my body: my stomach had begun attacking itself. But there was no routine test to find out and I didn’t have any symptoms," Johnson said in an earlier post addressing the diagnosis. 

Johnson, who grew up in a religious Latter-day Saint family in Utah but left the church in his adult years, has become a notorious influencer online in the health and wellness space, going to extreme extents in order to prolong his life, even swapping blood with his teenage son. 

Last Tuesday, he even made the claim that he was able to make a newborn clone of himself, but the experiment that he hopes to one day be a clone of himself "lives in a petri dish for now."
