Since GLP-1 drugs like Ozempic became widespread, rates of NION (non-arteritic ischemic optic neuropathy) — a sudden, painless, potentially permanent loss of vision in one eye — have doubled. Users appear to be 68.6 times more likely to develop this condition.

The conversation takes a timely and controversial turn when Sinclair reveals that his age-reversal eye therapy is currently also targeting NION — a condition whose rates, he says, have doubled since GLP-1 drugs became popular. Citing Harvard researcher Joe Rizzo, Sinclair says the correlation is robust and global. Rogan reads alarming statistics from Perplexity suggesting a 68.6-times increased risk for GLP-1 users. Both acknowledge that absolute risk remains low and that these drugs have likely saved millions of lives through weight loss and metabolic health improvements. But Sinclair's warning is clear: these drugs are not without risk, and the enthusiastic online promotion of Ozempic by people with financial interests in the drugs is doing the public a disservice. The segment is a model of nuanced thinking about pharmaceutical trade-offs.
A recent study found that tadalafil (Cialis), taken at 7mg daily, appears to protect mice and humans against certain cancers including head and neck cancer by exposing tumors to the immune system.
The incidence of NION (non-arteritic ischemic optic neuropathy), a type of sudden eye stroke, has doubled in correlation with the rise of GLP-1 medications like Ozempic.
Users of GLP-1 drugs like Ozempic appear to be 68.6 times more likely to develop sudden vision loss (NION), and rates of this eye condition have doubled since these drugs became widespread.
AI nailed Andrew Huberman's vertigo-vs-low-blood-pressure diagnosis because that pattern has been reported millions of times. But every patient's liver is different and data on liver surgeries is scarce worldwide — making solo robot surgery dangerous. The rule is simple: data abundance means AI can help; data scarcity means keep the human in the loop.
Fei-Fei Li's father had liver surgery performed by a da Vinci robot guided by a surgeon. The result: 10 times less blood loss than a typical procedure. This isn't replacement — it's the gold standard of human-machine collaboration, where the human's judgment and the robot's precision combine.
US drug overdose deaths fell from 110,000 to roughly 70,000 — the biggest CDC-recorded single-year drop ever. Men's rates fell 27% in one year, and the steepest decline of all was among 15–24-year-olds, down 37%. The crisis narrative around young men needs to make room for signs of genuine progress.
Kessler thought his grief expertise would protect him. It didn't. When his son David died unexpectedly, he found himself on the floor — and eventually realized that acceptance alone wasn't enough. That unmet need became the sixth stage: finding meaning.
Grief isn't just death — it's any unwanted change. Kessler lectured at Coca-Cola and General Mills not because they had lots of funerals, but because change management is grief management. People who grieve well live well.
Witnessing someone's grief isn't just emotional support — it's an essential act of healing. Kessler argues grief is a severance and connection heals it. But real witnessing has two steps: seeing the pain AND affirming the person's capacity to recover.
Avoiding grief isn't free — it's exhausting. Kessler's beach ball metaphor nails it: pushing a small balloon down is easy, but holding a massive beach ball underwater takes constant, draining energy. Unattended feelings don't disappear; they just consume you.
Most people try to control their environment to avoid triggers. Kessler flips this entirely: triggers aren't problems to manage around — they're a detailed map to your pain and your healing. Every trigger points directly to what needs attention.
Running from pain doesn't leave it behind — it accelerates the chase. Whatever we run from pursues us, and whatever we face transforms us. Both Kessler and Lewis Howes testify to knowing both roads firsthand.
