Tell me about someone really interesting that you know.

I take it I'm the first one to read the title entirely instead of spitting a fun fact. I live and work up in the rocky mountains, and ski patrol tends to be the most interesting people out there. They're paramedics, but because you can't just grab a paramedic out of the ambulance roller coaster tycoon style and simply drop them in the middle of the woods on the side of the mountain they're also some of the best skiers out there. So these are people with both medical and extreme sports training.

That's incredible. What training do they receive?
- Wilderness first aid at a minimum but I've heard them talk about how pay goes up the more certifications you get as far as medical goes. The initial ski trial from what I've heard is pretty rough (I've only done the ski trial for lift operations which consists of doing your morning commute in the dark with flashlights without dying).
I had an uncle that did that for years. In the summer he worked in silver mines and in the winter he worked ski patrol. He eventually quit because in his words, "I got tired of risking my neck for dumb rich guys who couldn't stay where they were supposed to."
He was also a cliff diver and lived in an honest to God log cabin. I spent a summer with him once where I had to chop all of his firewood for the winter.
The best memory I have is when he spilt his beer all over the living room and my aunt walks in and goes, "It smells like a Turkish brothel in here." My uncle completely straight faced answered, "no it doesn't." Well it turns out he spent some time in a Turkish brothel in the 70s as well.
I love talking to those guys on the lifts. Many of them are characters. Mad respect to all ski patrollers out there, I appreciate you every time I see you on the slopes!

I know a guy who used to be an LA County Sheriff's deputy. He took a vacation to go scuba diving and loved it so much he went home, quit his job, moved countries, and started his own scuba business in Mexico (which is how I met him). Lived there for almost 20 years and built an incredibly successful business because his customer service, attention to detail, and commitment to providing a great experience were top notch. He met his future wife there, who was from Spain. After many years they left Mexico and moved to Spain where he now lives in semi-retirement, in a really beautiful place straight out of the Gladiator movie, gardening and enjoying a peaceful life and going on adventures all over. I've rarely met anyone who chased their dreams so successfully.

Man can he and I be friends? That's incredible.

You can lose about 7% of your bodyweight in a single day before it starts to impair your performance. For a 180 lb person, that means you can lose almost 13 lbs of sweat. The average human stores about a day's worth of calories in muscle glycogen. Once you burn through that, you'll experience something called "hitting the wall". People who aren't trained for this will quite literally just... stop working. They'll fall over and not be able to move. With training, you can make your body better at burning fat to keep your muscles moving even when you surpass the limits of normal human endurance.

That IS really interesting, but OP said "someone", not "something".
- I'm not that picky tbh.
- I can't read 😭
- The marathon mountaineering girltwink sounds interesting

Anesthesia had to be discovered, forgotten, and rediscovered five times.

Also related to anesthesia, those of us with the red hair gene need 20% more of it for it to work.

Anesthesia is the most interesting topic I can think of! Like you literally can be knocked so unconscious and have bodily organs removed and be woken up and not feel a thing? That's fascinating.

I used to know this lady who was a retired cheff and now she did wildlife rescue. She would specialise in reptiles, so usually most of her calls were to remove snakes that got into people's homes. In particular I remember one occasion in which we went bushwalking with our uni course, and she spotted - and handled- a wild python for us to see. That was pretty cool.

That lady is bad ass!
