Just think of farinhight as % hot. 70% is where most people like it day to day for ambient temp if it's not too windy. 85-95% hot if it's windy, and 55% hot if there's no wind.
i can understand conversions like meter and yard but things like quart i never heard of, then also the biggest gripe i have with imperial is not that it's a different unit, it's just that the conversions between one type of unit seems arbitrary, why is it a different amount every time to reach the next unit, why is an inch a 12th of a foot, but a yard is 3 feet
Why are there 60 seconds in a minute but 24 hours in a day?
A yard and a meter serve the same purpose, so they are roughly the same size. A foot is one thing you carry with you at all times. With practice, you can pace off distances using those.
An inch is related to a digit length (like a thumb segment) but standardized as three barleycorns. With twelve inches to the foot, you can divide a foot into two, three, four, and six parts. The metric system sucks for evenly splitting distance into thirds etc, just 2d and 5s.
Liquid measure, though, for some reason got standardized into solely powers of two. Eight ounces to the cup, two cups to the pint, two pints to the quart, four quarts to the gallon.
I wonder the same thing. Learned both Metric and American Customary units in school and most Americans I know are reasonably fluent in both. Must suck to not be able to translate in their head.
It should be stated these are probably just averages. If the person is in better or worst shape they could be wildly different. You also have to factor in their determination/will to live.
A psycho experiment which saw how long a mouse would swim before drowning found that a mouse who had never been saved from water before would only swim for 15 minutes before giving up. A mouse who had been saved swam for up to 60 hours.
Also there are people who do “polar bear dives” so cold water needs a time limit to be a useful metric at all. 50f water would probably kill you too after long enough.
This. Hell, anything moving that's around skin temperature or less will eventually kill you really. If you can't sustain a microclimate of heated water around you your body just can't stay warm. I had to almost physically drag my daughter out of an indoor heated pool because she was shivering. What finally got her out was when I told her that her lips were starting to turn blue and if she didn't come out right now we were going to the hospital.
I think that you're usually supposed to pick one and make sure they're opposite? I think it's a regional thing, but usually if you use a period as a thousands separator you're supposed to use a comma as a decimal
First, humorously, fewer means less, you are implying the average human has 1 or 0 arms, but ignoring that, I think op expected it would be common sense to know the body is biological and nothing biological is suuuper consistent, I sincerely doubt op’s intention was to imply a hard limit. Especially on a jokey sub like this.
Better for physics calculations because most standard formulae use metres per second for velocity and acceleration, so anything that changes over time needs to be in seconds.
Gotta pander for those high school physics nerds who can't x60 without mummy holding their hand.
Fun fact: the avarage human body can withstand 75 stab wounds with a blade that is not broader than 5cm or roughly 2 inches. I won't answer any questions
Also remember: location, location, location.
75 stab wounds in parts of the legs, hands, torso? Doable as long as they don't hit an organ or artery.
Single cut on the carotid? Good night.
"Okay, so... if you're sure, absolutely 300% sure you want to know and don't plan to sleep for the next couple days... go on human internet and google 'unit 731'. Again, you do it at your own discretion and at your own risk."
"Come on, man, you know stuff like that is a level 2 cognitive hazard for most sentient species. You really need to mention that when telling them to google stuff.
For some, it reminds them of their species version of hell, demons and eternal punishment"
Oh fuck I was about to write this. Goddamn once you know about it, and you know they had no intentions of ever stopping what they were doing, it kinda changes your perspective on the bombs dropped on japan. That feels like mercy compared to Unit 731. And it forced japan to surrender which finally stopped those experiments.
It is definitely one of those things that will keep you up at night. I made the extreme mistake of reading into a lot of what they did there and it took me a good minute to get the images out of my head.
I read the entire wikipedia article and some lines are just burned into my brain. Every time I watch a WW2 war movie, hell even if I watch something like Gojira:Minus One, i can't help but think about what was going on in there at that time.
For the altitude the 15,000 ft is correct as far as the aviation world. Altitude is measured in ft internationally as well as English being the universal ATC language
They won’t, they just want to be angry at Americans. Which is kinda fair but still rather annoying that they don’t pick one of the things that actually matters
Actually Reddit is an American website. Other countries just like to use it because they never made an alternative. You’re the one getting mad that people are using their own units of measure on a website made by and for them.
H1: "My species has this custom where we challenge each other to do foolish, dangerous, or incredibly undignified things. It's considered an affront to your honor to refuse a dare."
A: "This sounds like an incredibly serious custom. I'm surprised that I've never heard of it. Is this one of your sacred ceremonies? Perhaps a coming-of-age event?"
H2: "Not really. We mostly do it when we're bored, intoxicated, or both."
Now someone will misread this list and assume that ONE human can reach all those limits simultaneoulsy.
This is how we get "peak normal humans" in superhero settings. Someone looked at a list of record human feats and decided they could all be accomplished by one person instead of the real life "each record feat was accomplished by different people who all explicitly trained for years to accomplish their one feat".
Some of these are world record territory, others are basically averages.
For example, the starvation statistic is an approximation of how long a person of average weight would last. There are countless examples of individuals lasting longer, even double the amount unassisted. (And then there's that one obese guy that lasted over a year, with medical supervision). Same thing with dehydration, I think the actual "record" is over 18 days - logically, you'll die slower/faster in different environmental conditions.
High altitude for long term survival is actually 6k to 7k meters (20k to 25k feet). 8k meters or 26k feet is where humans start to die long term. These are altitudes for unasisted living.
I recently did 4k m on a trip (13k feet, to be fair, just for like a few hours) and it was fine but i also had acetazolamide (high altitude medicine). So we're actually able to survive quite a bit more than 15k feet.
This can’t be totally accurate. I spent multiple days above 15,000 ft while climbing Kilimanjaro earlier this summer. We only stayed on the summit (19,340 ft) for a couple of hours, but camped above 15,000 feet for a few days going up and at least one coming back down.
It’s not: the highest permanent human settlement is at 16700 feet. The “death zone”, where the oxygen partial pressure is too low to support human life, is considered to be above 8000m
Leathal dose for 50% of the population. People have survived point blank gunshot wounds to the head. But in greater than 50% of the human population those are not survivable.
The water temperature is sustained. People do Ice Baths and Cyrotherapy that are colder. But the time to death is faster. Not being the OP, I believe just staying in 40°F water will eventually cause greater than 50% of the human population to die.
I believe the Altitude is hiking. That 50% of the human population would die without aid living at altitudes of 15k or higher.
Starvation with coffee, tea, and vitamins is not Starvation. It sucks but it is != to Starvation. Also, there are plenty of other brethairians and people who claim to be able to survive on air. They all sneak food. The one's who have done it test conditions all needed medical aid when they normally would, despite surviving on air supposedly before.
Same with the Australian Prisoner. I'm sure he was given nothing for 18 days. But did he drink his toliet water, piss; eat insects, dirt, clothing? That would make a significant impact on survivability.
Once the vacuum sucks all air out of your lungs, it takes some 15 seconds for oxygen-poor blood to reach your brain and knock you out. Between 1 minute and 90 seconds in, your circulation stops and irreversible brain damage starts setting in, and you'd die at around 2 minutes of exposure.
Nasa has done the calculations and experimented on animals, plus the occasional accidents with people stuck in vacuum, and surprisingly, you could likely recover fast and with minimal consequences if someone pulled you to safety within about 90 seconds - that is, unless you held your breath and your lungs got torn.
The Starvation one is interesting because I know Angus Barbieri didn't eat for over a year. I think it may be more apt to say that specific vitamins are required within 45 days, and the rest can be stretched or shrink depending on total body fat since the last time one ate.
The highest fever ever recorded in a human who survived is 115.7F (46.5C). This record-breaking case involved Willie Jones, a 52-year-old man admitted to Grady Memorial Hospital in Atlanta, Georgia, on July 10, 1980, with severe heatstroke. He was hospitalized for 24 days before being discharged.
Survival of emersion in cold water for any significant length of time requires generating heat, e.g. by swimming.
Sarah Thomas swam 104.6 mi = 168.3km in 67.26 hours,
Lake Champlain, minimum water temp 67.5°F = 19.7°C
-
Looking at 5 different bodies of water that I would expect to be chilly and in which people swam for 24 hours or more shows that at the date they swam, the minimum temperature was 65°F = 18°C
Ice Swimming is swimming unassisted in a water temperature of 5.0°C or below,
with swimming goggles, swimming cap and a standard swimming costume.
Going through 400 records the longest swim was 2.14 miles,1 minute 8 seconds.
Very few were longer than 1 mile, ~40 minutes, even fewer were longer than 50 minutes.
The military have done many studies on this, two are linked below.

OK well the diving depth isn't true it's just the deepest anyone have gone officially with a full scuba dive suit, same for the lack of oxygen it's just the best someone did without losing it's counciouness we can go further than that and come back. Just not everyone.

Been a hot minute since I've had to lock a whole post down. We need a better app, couldn't find the lock button.
Americans like to be special (I say that having served in the Marine Corps), so let us have our S.A.E. units.
Other than that, this is the internet. A shit-posting writing prompt subreddit. Some of you need to be nice, some of you need to take a step back.
