This YouTube interview (uploaded by Jeffrey Jaime, CISSP) features Ben Greenfield describing his accidental cold-plunging practice from years of triathlon/open-water swim training (e.g., swimming in ~45°F open water, YMCA pool ~69°F) and linking that experience to metabolic benefits and the later popularity of cold exposure. The conversation then moves to nootropics and biohacking—Greenfield recounts older biohacking stacks (peptides, high-dose choline) and states that R-modafinil sourced from an Indian pharmacy can produce prolonged focused wakefulness ("12 to 16 hours").

Chapters

I was just accidentally cold plunging because I raced triathlon for like 15 years and you just had to swim come hell or high water. Like you'd be swinging your arms in your speedo getting ready to jump into the YMCA pool that was you know like 69 degrees when there's a 45 degree draft coming in the door. In Idaho in the winter, you'd have to go out and do open water swimming in October to get ready for Hawaii Ironman. And the only body of water outside your house in October in the inland northwest is like, you know, 45 degrees. So I was doing it accidentally before I lear about all the metabolic benefits. And then it got pretty popular.
Like if you, when you are in that zone, when you're focused, you do you like to supplement with anything other than caffeine or nicotine, anything like that?
There's all sorts of fantastic compounds out there. You know back in, back in like the, the, the old school biohacking days, I mean people had all these kind of things like paracetam and new peptide and you know, high doses of choline, all sorts of stuff you'd order from only sold for human research chemical websites and you kind of put your own stack. Some of that stuff does work like I would say probably the most powerful would be like go to like, you know, you can get R. Modafinil from an Indian pharmacy and that stuff will just like keep you going for like 12 to 16 hours non stop focus.
