Saul and Lydia walk through the practical follow-up to last episode’s HomePlunge H3 review — the exact gear (a bath filter, two overflow covers, and a piece of tape) and the step-by-step routine Saul uses every time: finding your water line, prepping the filter and overflow cover, and solving the slow-drain problem with a two-timer trick. It’s the whole system for how to turn a regular bathtub into a cold plunge you’ll actually use.

Saul and Lydia get into why the HomePlunge H3 replaced Saul’s old backyard tub-and-chiller setup — the maintenance, the weather excuses, and the dopamine research (a roughly 250% spike from cold water immersion, per Šrámek et al. and Andrew Huberman’s cold exposure work) that explains why the habit actually stuck this time. They cover how the H3 works, what a year of daily use looks like, who it’s actually for, and why moving the whole thing into the bathroom removed every excuse Saul used to have.

Saul and Lydia talk through the “Free Books and Cold Waters” setup by Saul’s front door — a Yeti cooler, a plastic box of books, a short printed testimony tucked inside each one, and a simple invite card to church. They get into why it works on a delivery driver’s thankless, tightly-scheduled day, how to build your own version step by step, and the two books that shaped how Saul thinks about small acts of service as evangelism: Conspiracy of Kindness by Steve Sjogren and Servolution by Dino Rizzo.

Saul and Lydia dig into why The Pour Over earned a permanent spot in Saul’s rotation — a newsletter with over 1.6 million readers that became a daily-ish podcast, hosted by Joe Kim, with quick Monday/Wednesday/Friday hits and a deeper Saturday “TPO Explains.” They talk through the built-in bias check (editors from across the political aisle review every story before it airs), who the show is actually for, what a typical eight-minute episode covers, and the couple of things worth knowing before you subscribe.

Saul walks through the one-minute Mac setting that swaps blue light for red at night — Accessibility, Display, Color Filters — plus the menu-bar shortcut that makes it actually stick, and the one keyboard combo to avoid (it audibly announces itself, at the worst possible time). Saul and Lydia also cover why the same trick works on iPhone, iPad, and Apple Watch too.

Saul walks through the specific ways he actually uses AI every day — not hypothetically, but this week: catching hype in ads before he buys anything, tracking down the exact product he wants without scrolling forty listicles, translating testimony into Spanish with almost no corrections needed, building presentation images in under an hour, and untangling supplement interactions and doctor’s notes before a phone call. Saul and Lydia talk through why he splits the work between ChatGPT and Claude instead of picking just one.
