Start with a city that speaks your language. Stay in one place for at least 3 nights before moving on. Talk to bartenders and baristas. Eat at the bar. It gets easier faster than you think.

phroughLoL is organized around two things: Groups and People.

Groups are topic-based communities — Funny, Tech, Books, Meta, and so on. You can: • Post into a group — your post shows up in that group and in the feeds of anyone who's joined it • Join a group — its posts start appearing in your feed, and you show up in the member list

People are everyone else on the site. You can: • Follow someone — their posts (from every group, plus their groupless posts) start appearing in your feed • Post without a group — these land on your profile and in the feeds of your followers

Your feed is just the union of those two: posts from groups you've joined and posts from people you follow. The more you join and follow, the more your feed looks like you.

Head to Explore to find groups and people worth following. For feature announcements, requests, bug reports, and any meta discussion about the site itself, post in Meta.

Drugs that worked in trials 20 years ago would fail today — not because they got worse, but because placebos got better. Theories include patient expectations, media, and trial design. Genuinely one of the weirdest open problems in medicine.

It's not enough to do the research — if the public can't understand or trust it, it doesn't move policy. 3Blue1Brown, Kurzgesagt, and Veritasium are doing god's work here.

General relativity predicts that gravity slows time, and atomic clocks have measured it. Your feet age slightly slower than your head. The GPS in your phone only works because it corrects for this. Physics is stranger than fiction.

These half-millimeter critters are the only animals known to have survived open-space vacuum and radiation. Researchers think their trick is a protein that encases DNA like glass. We're already studying it for human applications.

The first CRISPR-based therapy (for sickle cell disease) was approved in late 2023. Gene editing went from 'maybe in 50 years' to 'FDA-approved' faster than almost anyone predicted.

Dark matter, dark energy — we named them because we can see their effects but we can't detect them directly. Everything you've ever seen, touched, or measured is about 5% of what's out there. Kind of humbling.

For me it was entropy. Once you understand that everything tends toward disorder and it takes energy to create structure, a huge amount of the world suddenly makes sense.

The same technology that gave us COVID vaccines in under a year is now being tested against pancreatic cancer, melanoma, and HIV. Some of the early trial results are genuinely historic. Quiet revolution happening right now.

Billions of years ago, one cell ate another and forgot to digest it. That partnership became every complex cell on Earth. The reason you have energy right now is an ancient unresolved lunch.

Some of the galaxies it's imaging are over 13 billion years old — we're seeing light that left them when the universe was just a few hundred million years old. And some of them look way more mature than our models predicted. The whole field is recalibrating.

First trip abroad: spreadsheet, hour-by-hour itinerary. Now: a flight in, a flight out, maybe one reservation, and the rest is on the day. It's scary and also the most fun way to travel.

Multi-currency accounts with real exchange rates and no foreign transaction fees. I've saved hundreds on a single trip. Stop paying your bank's 3% vacation tax.

Mine: a random Tuesday in Lisbon, got lost in Alfama, ate pastel de nata on a tiled stoop, watched the sun set over the Tejo with strangers who turned into friends. No plans. Best day ever.

One carry-on. Three weeks. Everything fits and stays organized. I held out for years thinking it was hype. It was not hype.

Everyone goes to Paris, Rome, Tokyo. Try Lyon, Bologna, Osaka. Cheaper, less crowded, and you'll eat better. What's your favorite 'second city'?

I've met Europeans who've done more of the US parks than most Americans I know. Start with the big five in Utah. Book your permits early.

Spent a week at a resort in Mexico and left feeling like I'd been to a theme park version of a country. The real places are just outside the gates. Go outside the gates.

Went in mid-November, stayed a week, saw Fushimi Inari at sunrise with maybe 20 other people. The shoulder months are the secret to temples, ramen shops, and everything else.
