Questions you'd like answering, regardless of how trivial they may seem

I got a medical check up where the nurse asked if I drink enough water and she said I will know by the colour of my urine. It got me thinking about how much water our ancestors drank and I assumed it wasn't much (compared to today). I'm that case, out bodies are fine with not drinking too much water and perhaps there was too much emphasis on staying hydrated these days.

Yep, I doubt the Bedouin drank as much as we do and they are still about.
