can your body take water from the bladder or once it's there it's no-go.
let's say i drink a lot of water at once and i feel the need to pee but don't pee, then i don't drink water for a while. would the body take the water from there?
i know this seems weird but the whole point is that wouldn't it be more practical to not piss at all than to piss and drink it in survival situations. i know none of this is practical but just ignore the kidney and look at it from only a avoiding dehydration perspective
