I'd say you are right about the water. It takes bout 18-24 days to starve to death if you get some water, but lasting a week without liquids is difficult. -Tom
A rule of thumb I’ve heard is seven. Seven minutes without air, seven days without water, seven weeks without food. But you’re going to be uncomfortable with three of each.
” It takes bout 18-24 days to starve to death if you get some water,”
An average human, if healthy can go 30-40 days without food.
I would bet most Americans have the fat reserves to go longer than that. Being stuck in a collapsed building like that might be one of the only times having a little extra weight would be a good thing!
People can go longer without food depending on fat reserves. Water / hydration will kill them much faster.
