Cannibals

"If you were to eat another adult human being, it would be approximately 125,822 calories. I went down a rabbit hole on Google and yeah."

ItsmeTrev

"How come it's almost 126K?"

Blablabblue

"Math. Average human is say 70 kg, has 20% bodyfat, so 14kg of fat. Fat has 9kcal per gram, which makes it. 126,000kcal. Math never lies! But I do make plenty of mistakes. Probably it's more complicated - but directionally seems legit."

Decay

"Within three days of death, the enzymes from your digestive system begin to digest your body."

"I guess it’s reassuring to know your body decays before bugs can even get a shot to help your body decay, sort of like a medical death except your body willingly does it for you instead of doctors."

Jigsaw_isnt_a_puppet

"My Uni mate is a navy submariner and he said that if a problem isn’t your department you just ignore it, because ultimately it either gets fixed or you die, neither of which are scenarios you can do anything about. Him and a friend were playing Fifa in their bunk when the whole sub tipped to 45 degrees. They just kept playing at 45 degrees… it got fixed eventually but they’re reactor crew so nothing they could do to help either way."

"body farms"

"There are places called 'body farms' were scientists and researchers look at the decomposition process of human remains in different circumstances. Basically a big area somewhere outside were human, sometimes pig corpses are laid out to be exposed to the natural elements or they're even enclosed somewhere (like the trunk of a car). They're actually important e.g. for forensic anthropology to help solve crimes. And you can donate your body for research after you die!"
