Memorable Quotes:

• “The more pain you experience, the better the rush, the better it’s the endorphin high people talk about.” – Dr. Patrick describes the mechanism behind the endorphin rush after intense exercise.
• “It’s really interesting how also you have this connection, but it’s a balance where you’re forgetting things that you’re you’re totally disconnecting some connections between old neurons that you had previously made for whatever thing you had learned or and you’re making room for this new neuron that just was born to make a new connection and make learn something new. So you have that balance.” – Dr. Patrick explains the brain’s capacity for learning and forgetting as a balancing act.
• “I think, I mean, there’s a lot of different things. Serotonin release is happens to a variety of different factors. But one one could actually be very potent, something that’s very potent that you’re experiencing. Do you know? Does that make sense where it’s like, it’s not just your everyday stuff that you kinda block at. Like, it’s just routine, but it’s something just novel and…” – Dr. Patrick discusses the role of serotonin in memory, particularly for emotionally significant events.
• “The human gut produces mono aminoxidase, which makes dimethyltrip to mean it doesn’t it kills it in the gut so that if you consume grass that has DMT in it, you’re you don’t have a psychedelic trip. but I don’t know if a cat has the same gut enzymes.” – Joe Rogan highlights the difference in how humans and animals process DMT.
• “So, you know, I’m definitely right about some some of these things… But the whole vitamin D thing. Vitamin D 3 is important, and I think it’s something that most people are, 70% of the population is not getting an adequate, you know, 70%.” – Dr. Patrick emphasizes the importance of vitamin D and its potential impact on health.
