    Also, don't eat yourself. The energy cost of recovering from the wound is significantly greater than the energy gain of eating a limb.

    I had mild frostbite as a kid, until explained, I thought it was odd they were wanting to ensure the water was as cold as possible before they put my feet into the tub. That ice cold water felt very warm, while I was too young to grasp the science, I immediately grasped their reasoning.
  • My daughter was stung by a jellyfish once. I remembered the vinegar trick and took off to the nearest store but they were out of vinegar so i bought pickles and poured the juice on her foot. It helped a lot
  • In Australia, unless you’re bitten by a snake in Victoria or Tasmania, don’t be overly concerned with identifying the snake. We have a ‘universal’ anti-venom for snakes found in the rest of the states/territories. It’s still better to use the specific anti-venom if you are able to identify the snake, but it’s not worth risking another bite to do so.

    I was really hoping #8 was in there. When diving in the Great Barrier Reef (when it was alive), I asked the guide what happens if you pee on a jellyfish sting. He replied "Well nothing, but you gonna have a pissy leg, mate."
  • @chrisleach4245
    My grandma told me about her brother that came in from a blizzard and his wife put his hands in hot water breaking the bones in his hands. It was in the 1930s and he was almost killed by it. My grandma lived to be 100. She was born in 1905 and died in 2005 she had seen more in her life than a lot of people who live today will.

    In Australia a lot of rural schools teach basic first aid including how to treat snake or spider bites. Since we are predominatly desert we also learn to take extra water, food and fuel for longer trips. The majority of fatalities are from city slickers who have no idea and just decide to go on a trip without preparation.
  • @ScotteiCovers
    Someone: Ouchie ouch I got stung by a jellyfish I wish there was something to make it stop hurting Some dude with a piss kink: Oh you haven’t heard?
  • @dp7933
    Surprised phase change wasn't explicitly mentioned regarding melting snow. Heating water one degree takes an enormous amount of energy. Heating ice one degree to turn it into water takes far more energy because of the phase change from solid to liquid (and now your body still has to heat the resulting cold water up to body temperature).

    "Cactus juice won't make you high like Sokka in atla" Those bastards lied to me
  • @TheDevler23
    I'm from the Pacific Northwest. Moss grows on every side of trees. I remember hearing that survival trick to follow the directions of the moss, and I remember laughing. You'd just go in circles, up here!
  • @NimhLabs
    Are you suggesting that Cactus Juice is NOT the Quenchiest? That it will not Quench me? What is next, the giant mushroom is not friendly?
  • @joecope9935
    The moss on trees has taught me that, in the Pacific Northwest, ALL directions are North!
  • Considering this video advocates the completely passive approach (like that works either), I would like to insert one good survival tip for the 'moss on the north side' situation. If you are where moss is growing, there will be flowing water somewhere, however small a trickle it is. Find it and follow it. Water does not flow in a circle. Water leads to more water and ultimately to people where ever you are in the world. everybody knows this, but in this discussion, it bears repeating.
  • I was stung by a jelly years ago and the lifeguard had a spray bottle full of a mixture of vinegar and seawater. Completely eradicated the pain and I was back in the water a couple minutes later!
  • @curingyou
    Me:*dying in the wilderness* Hank: simply go to the hospital
  • @jeandevine7835
    Thanks for this. Most of these I already knew, but that "urine on a jellyfish sting" is actually taught in scuba diving first aid, along with vinegar. I did get stung by a jelly once when scuba diving & opted for the vinegar over urine treatment. The vinegar did the trick.

    3:01 "Drink cactus juice! It'll quench ya, nothing quencher, it's the quenchiest!!!" xD
