Showerthoughts

A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The most popular seem to be lighthearted clever little truths, hidden in daily life.
Here are some examples to inspire your own showerthoughts:
- Both “200” and “160” are 2 minutes in microwave math
- When you’re a kid, you don’t realize you’re also watching your mom and dad grow up.
- More dreams have been destroyed by alarm clocks than anything else
Rules
- All posts must be showerthoughts
- The entire showerthought must be in the title
- No politics
- If your topic is in a grey area, please phrase it to emphasize the fascinating aspects, not the dramatic aspects. You can do this by avoiding overly politicized terms such as "capitalism" and "communism". If you must make comparisons, you can say something is different without saying something is better/worse.
- A good place for politics is c/politicaldiscussion
- Posts must be original/unique
- Adhere to Lemmy's Code of Conduct and the TOS
If you made it this far, showerthoughts is accepting new mods. This community is generally tame so its not a lot of work, but having a few more mods would help reports get addressed a little sooner.
Whats it like to be a mod? Reports just show up as messages in your Lemmy inbox, and if a different mod has already addressed the report, the message goes away and you never worry about it.

Humans are mostly water though.
And your scale makes even less sense because you are ignoring time and air moisture (for the maximum temperature). You would probably die very quickly in a 120°C hot sauna if it had 100% moisture.
Same with the cold: I'd not survive much longer than a minute in -50°C without clothes but with adequate protection several hours seems possible.
minimum and maximum body temperature (we are measuring humans, not the environment). I thought mentioning 50 as "normal human temperature" it was clear I was talking about body temperature
But the lowest body temp ever survived was 56.7F. making a scale out of that would be difficult because the distance from normal body temp to death is a lot closer on the upper range.
Fahrenheit is more of a scale of how the temperature feels to a human.
Fahrenheit decided to define the lowest possible temperature as 0° to avoid negative temperature, and the normal body temperatur of humans as 12°. Yes, he lived pre-metric times. Of course he soon realized that these big jumps of the 12° scale were pretty unusable, so he redefined an 1/8^th° of his first draft as the steps of his final scale. I don't know whether he lived to realize that the coldest temperature he could achieve in his lab was not the coldest temperature possible. Oh, and he got the body temperature slightly wrong. Still pretty impressive achivement for 1708.
Somehow I'm a bit sad he didn't keep the 12° scale. Just imagine Americans would have to take fever like: "the patient has 12⅞ °F".
But the lowest body temp ever survived was 56.7F.
Fahrenheit is more about how the temperature feels to humans. 0 is really fucking cold, and 100 is really fucking hot.
Ah, that makes a bit more sense.
Maximum body temperature should be pretty obvious - at least with one or two degrees (Celsius) of wiggle room.
Though, with minimum body temperature, do you mean minimum while conscious or minimum survivable? Because there have been cases where people were successfully resuscitated after being submerged in freezing water for a very long time:
