The guy in the story basically survived 6 days without water and traveled up to 160 miles during that time. It's almost unbelievable. I thought that once you loose 4-6 kg of water due to sweat the body does not function any more due to the changed concentration of minerals in the cells.

You risk heart attack even if you are in water only diet (without salts and potassium) for longer periods of time (several weeks).

Stupid question, but if stuck in the desert you can suck on some rock to recoup some lost minerals, no?

I guess like any deer we'd immediately recognise (and love) the taste of rock salt

That basically only happens if you do a water fast with distilled water.

Regular mineral water will avoid that.

When I read these stories, it's like a reminder of the incredible, albeit rare, resilience of the human body
