"I'm using Claude Code with various APIs to do tons of inbox analysis. I'm doing a 20-year retrospective analysis of angel investing — who made what introductions, which companies did I not reply to that ended up being successes. To do that manually would be impossible. It would take me a year full-time with multiple people. With Claude Code, Gmail API, and leaving my computer running for a handful of hours a few times, what you get back is credible. It's unbelievable."
▶ 1:03:08"Oh my god, you kids have it good now. I love ChatGPT and Claude and so on. It's so much easier. You need to know how to interrogate the system."
"Let me pop open some mockups that were created using Claude in an incredibly short period of time. It is just insane what you can do these days."

"I've played around with a lot of things in my earlier days and a lot of it is very, I would say, capped risk. If you're experimenting as I was with first generation Dexcom continuous glucose monitors in 2008, right? They were or 2009 very unpleasant to wear."
▶ 2:16"I was using a Gen 1 Dexcom, which was like sticking barbecue tines under... This is a continuous glucose monitor."

"No, I don't hate creatine. I love creatine. I just don't find it to be the most helpful for climbing specifically... I was taking 10 grams a day, but I started getting really wicked muscle cramps... I dialed it back to five. No cramps."
▶ 24:57"No, I don't hate creatine. I love creatine. I just don't find it to be the most helpful for climbing specifically... creatine can be your friend and sometimes not so much. If you overdo creatine, it is a problem with the GI."

"Beta-alanine was something that I surfaced again, and I wanted to see if it had ever been applied to climbing. And it turns out that there have been studies done specifically with elite climbers... I think this stuff has really helped. To the extent that my coaches, like it was almost by the clock. Like when I got to two and a half weeks of taking this, not before, they were like, 'Whoa. What happened?'"
▶ 0:17"It turns out that there have been studies done specifically with elite climbers... 57% longer before falling versus 19% improvement with placebo... I've been very impressed... This is Thorne Beta-Alanine SR, that means sustained release, to minimize... paresthesia."

▶ 3:13"I predosed with something called D-cycloserine. And I did one day and Dan this time around boom it was just like a switch basically the next day."

"I'm traveling with Maui Nui as usual. I probably get 40% of my protein from Maui Nui venison. This is wild harvested axis deer from Hawaii — incredibly nutrient dense. I treat this like a multivitamin. I give her probably two or three of these a week. Like every professional team you can imagine uses these things in their training. This is made with wild harvested venison, liver, and heart — organ meat — and you do not taste that."
▶ 38:03"There's a company that I'm involved with. It's probably 30% of my protein calories called Maui Nui. Maui Nui venison. It's wild harvested venison from Hawaii. And it's the most nutrient-dense red meat you can buy. Period. Full stop."

"Airofit, please improve your app if you haven't in the last year because I found it to be incredibly difficult. Plus your baseline of programming for somebody who's bought a device should be decent."
"I have also tried CBN specifically, which has been recommended to me for sleep and have not found it as effective."
"This is Google and it is a serious place of work. Please do not use Comic Sans."
"I still can't believe that the Dexcom app doesn't give you some estimate of caloric content or macros. It's just like you ate chicken. I'm like that's not helpful."
"I have tried modafinil. I've tried the various amphetamines — Adderall, Ritalin, etc. And the difference is that if I use modafinil for two or three days and I stop, I immediately feel a physical requirement to use it to get back to my prior baseline. That does not happen in the case of coca."
"I've tried Peloton and didn't like their ergonomics and so on for a bunch of reasons."

"How to Change Your Mind, a book by Michael Pollan that really shifted the tectonic plates of what was possible for psychedelics in the US and elsewhere. In some ways, in a lot of ways, in many, if not most of the best known philanthropists and supporters of psychedelics, not all of them, but a very high percentage, would kind of reach back to that as the tipping point for their interest."
"Michael Pollan's exceptional book how to change your mind right that might be the cutoff for before and after"
