Wtf are you even talking about, nothing I have said is speculative? My previous statement was of course meant as hyperbole, but was also phrased in a way to make it as accurate as possible. Instead you seem to be unable to realize that and are concentrating on unlikely edge cases. Not to mention TBI can literally change who you are.

If people are in freezing water for an extended period of time the start to go into hypothermia. Symptoms of hypothermia include:

Weak pulse

Clumsiness or lack of coordination

Drowsiness or very low energy

Confusion or memory loss

Loss of consciousness

Now does this sound like a state of being in which persons could climb the side of a boat en mass and cause it to tip? Adrenaline only lasts for so long.

At NO point did I ever say in 5 minutes any or all boats should have gone back. The ONLY 5 minutes I have referred to is your time in 'glacial water'. In controlled conditions, with no panic or fear. As well as being in good medical condition, no malnutrition and no history of nicotine use. I'm sure with a warm tent or whatever nearby.

But I'm do e arguing with some Jackass who dipped his toes in cold water and think he's an expert on cold water survival.
