teenagers carrying and using guns in baltimore actually is a real problem

Sure, but this school is in the county, outside city limits. In my experience, what passes for "sketchy" in Essex MD is roughly "random dude selling pit beef out of a barrel in front of his house", i.e. fairly benign. But it's admittedly been a long while since I lived in Baltimore.

why the tourniquet?

I was curious about that myself.

"To slow absorption of injected antigens (e.g., insect stings), a tourniquet may be placed proximal to the injection site. "

https://www.aafp.org/pubs/afp/issues/2003/1001/p1325.html

The article says that tourniquets are no longer recommended. It doesn't seem like a tourniquet would be of any help if you ingested something but reasonable for insect stings. Anyone who has taken a first aid course gets warned multiple times about the danger of leaving a tourniquet on too long but maybe random people aren't aware of it.

sometimes professionals need to fix shit and need exacting clarity

Words of Latin origin are identifiable at a glance, and homonymic collisions are thereby avoided

-- Caeser, seizer of the day

"Caesar" was pronounced in Latin with a hard C, which is preserved in German ("Kaiser").

And v is pronounced like w, but people look at you funny if you pronounce vice versa "wikay wersa".

I made someone with a veni vidi vici tattoo when I told him that.

yes, i've seen that done in videos of streetfights.

i had the same experience. my solution was to configure youtube kids to only show my whitelist of mannually approved videos.

is it not true though that activity/threshholds of dopamine synapses can be globally or semi-globally up and down regulated?

It is not true.

It’s unfortunate that so many podcasters have leaned into the myths about being able to manipulate dopamine as some global up/down thing you can adjust by following certain protocols.

Andrew Huberman is among the worst at this because he has enough education that he should know better. I think he’s too enamored with the traffic and clicks he gets when he talks about dopamine, so he’s willing to stretch the truth or even break it completely if it will make for engaging podcast content.

Some of the studies he cites over and over again about dopamine don’t even say what he claims. Huberman is a joke among people who actually know the science, but he became a hero to people who thought he was just a nice guy sharing free knowledge with them.

Would you say the harm outweighs the good Huberman does with his ability to communicate complex concepts in ways that are more digestible to laymen?

Not true. Down/up regulation happens in areas where (sometimes called) psychoactive substances and/or regulatory nervous signals reach. Substances that cross blood brain barrier still might not reach areas due to lowered blood flow or tissue damage.

And dopamine cannot cross the blood-brain barrier.

No, activity and expression are always local. Exclusively. There are no global levers.

I'm pretty sure there are things that affect the brain globally... nutrient availability? Oxygen availability? Sledgehammers?

i would think some of our taboo words that a re borderline illegal and I am scared to even type the first letter of with asterixes because i am on a work computer

If I could change one thing about Duolingo, it would be to allow the user to turn off all the gamification completely. I don't care about fake internet gems, knowing how to speak Chinese (or whatever) is it's own reward, so stop wasting my time with bs!

Nevertheless, Duolingo is an amazing and convenient starting point for unlocking the learning of new languages.

Make your way through the entire course as fast as you can, while also listening to music, talking to people, talking to chatGPT, reading books, etc in the target language as soon as you can manage.

Protip: learn your 3rd language using your second as the language of instruction.
