How long does the average victim survive in a well before finally succumbing? I picture it being only a few (like 3-5) minutes, but does it sometimes drag out longer?
IF the person fell head first and was 100% immediately suffocated without ANY air (picture a rear naked choke) then yeah, 5 minutes tops. that however is usualy not the case. I would imagine the death to be much more gradual, slow, torturous. Perhaps hanging upside down all night, then eventually dying from hypothermia.
