I'm gonna try to explain this despite being drunk:
Eberyone who's "spontaneously combusted" have been smokers.
Especially smokers in bed

When they fall asleep in bed, with a smoke intheir hand, their clothes catch on fire. If it's left on fire lomg enough, the fat on the human catches on fire.

Fat is especially flammable.

Because a human has alot of fat throughout, especially in the belly/chest area, that the most flammable.

Long story short: Human spontameous combustion comes from smoking in beds that leads to sports couches to make kids smoke in bed cause it's "safer", then they fall asleep in bed, with a lit cigarette,lighting their clothes or bed, leading to the kid burning, leading to their costudents catching fire and eventually thw whole school to catch fire, leading to several death.

It’s happened a few times. It’s never been observed under laboratory conditions, however. The few times it has happened, it’s turned out that the person’s clothes were soaked in flammable liquid and they had friction matches in their pocket.

Bean chilli will do that to u
