Quick Water Question

[Lightspeed]

Hi S13

I have some documents about maritime survial issues. I goes into how much water needs to be rationed out just to sustain life in an open life raft. I don't remember the volume but it was a small fraction of the recommended 2l per day.

I've also read that the famous 8 glasses per day has no traceable research, and that it was reckoned to have come from bottled water companies' PR.

2l per day is on the high side for me, unless I am very active and or the ambient temperature is high.
