We were always taught the rule of 3’s.

3 minutes without air
3 days without water
3 weeks without food.

The longest recorded fast in human history was 382 days, but the man who did it, Angus Barbieri, weighed about 450 pounds, so he had plenty of "stored energy" to spare.

Angus Barbieri's Fast

I have personally done 5-day fasts and I currently do a quarterly 72-hour fast as well as 2 fasts per week of at least 36 hours. Obviously this is nowhere near 3 weeks, but I know of people who have done 28-day and 40-day fasts as well, consuming only water, tea/coffee, electrolytes and vitamins. There is another man in more recent times (name escapes me) who documented his 55-day fast on YouTube.

I wouldn't even attempt 24 hours without water and will hopefully never be in a position where I had to do so.

We’ve got to protect our precious bodily fluids.

And, if you’re hungry and thirsty - and there’s food, but no water around, DON’T EAT - it takes water to process food and you’ll die from dehydration even faster....

I thought beer was dehydrating

I do not avoid women. No, not at all. But I do deny them my essence.

Eh. The headline smacks of a SHTF survival question, but the author outlines a puff piece for media idiots. Did you not read it? Total garbage.

In contrast, I prefer the question posed to progressives placed in deep water with 5lb around each ankle:

“How long can you tread water?”

“””” there’s food, but no water around, DON’T EAT - it takes water to process food and you’ll die from dehydration even faster.””””

Also, assuming a survival situation for a hunter is about overnight, to 3 or 4 days, I tell them to skip worrying about food, don’t expend a lot of energy looking for berries and don’t take up space in their belt kit, with survival gear to fish and hunt rabbits and such.

It is, based on the ethanol/alcohol.

But, beer is mostly water.
