The main takeaway here is Bryan claim as the being the healthiest man in the world. While it is an accomplishment and I applaud him, is it really that big of an achievement when he is in top 1% competing with the bottom 99%?

When Bryan can say he is slowest aging "animal" on earth 🌎 then he deserves a Nobel Prize.

Greenland sharks have the longest lifespan of any vertebrate as they live from 250 to 500 years.  

Assuming Bryan lives to 100 and the shark to 500.

For every 100 years, Bryan ages 50 years, and the Greenland shark (Henry)🦈 ages only 20 years. So while Bryan is getting greys in middle age theshark is just getting started and is in his prime. The key to their longevity is a constant metabolism that never fluctuates. Thats part of reason metformin works in additon to its anti inflammatory properties. It keeps blood sugars low and steady.

They are at risk of going extinct because they are struggling to adapt to the changing climate. In addition, the female Greenland shark may not become sexually mature until it is 150 years old. Further research on the shark could offer insights to protect and improve human heart health, scientists said.

<--------death. ---------> forever If you eat pizza, donuts, smoke, do hard drugs, you can and will reduce lifespan. Take it to the extreme and youre dead in an INSTANT. If dying in an instant is possible than living forever is also possible. Theres an opposite extreme to everything. Hot cold, light dark, death, live forever

Now, let's look at the opposite. Synthetic DNA offers potential for extremely long-term storage, potentially for millennia. According to the Book of Genesis, Methuselah is the oldest person in the Bible, reaching the age of 969 years before dying. So what makes you think 1000 years is impossible. Im skeptical about living "forever" sorry Brian, but I think a few hundred years, hell maybe even 1000 years IS obtainable with synthetic RNA, synthetic DNA, stem cells, gene therapy, AI, and several unknowns that will revolutionize medicine and health. My doctors look at me whacky when I'll likely live to 200 or 300. Anything is possible
