Tough call on that one Black Blade..
Longest I have gone without food is 8 days..
Just in some bad circumstances, where we absolutely could not get re-supplied.
My Bros arm started looking like steak.
It really becomes, my .02 a matter of discipline.
We all were in the Military and not sure if that made a difference.
Not one man complained, we just accepted our situation.
I say water, before food, will cause the brain too shut down.
Food your body will start eating itself, till you die.
No water and your body goes into involuntary convulsions.
Oh God did we have water, too much.
Now 15 days?
I guess true..
My Bro would be home now and people asking.
"Damn dude what the hell happened too your arm, looks like someone chewed the damn thing off."
