My parents drink ZERO water (Page 2)

I saw a show on TV, it was produced in the UK, where they test out various theories in real life situations.  It is not necessarily scientifically valid, but it is interesting, and they do throw in some scientific measurements.

They took twin girls that were about 25 years old, and they weighed about the same.  Told one to drink at least X amount of glasses of water, while the other was not able to drink any water, for a few days.  They were testing if drinking a lot of water makes your skin nicer.  They used some instrument that measured the water content of your skin.  Before the trial the water content in their skin was almost exactly the same for both girls.  After the test it was almost exactly the same too.  In the end they surmised that the girl that did not drink any water, got enough liquid just from the foods she ate.  Then they did a little calculation to determine how much liquid they got from food.  I don't remember the numbers, but it was significant.

While this is one small test, it was very interesting.  I don't believe there is any scientific study validating the "8 glasses of water a day, or else" movement.

As far as coffee, they have tried and tried.  They have spent a ton of money on research to find some way that it is bad for you.  They have come up with nothing.  Nothing. 

BTW, I like coffee.  I drink two cups a day.  Whether I need it or not.  Besides that I only drink water (or sports drink when exercising).

As long as you go pee a few times a day, you are probably all right.  IMHO

For the record, I've (briefly) met Lisa's parents and they aren't nearly as dry as she makes them out to be.

Her dad also didn't appear to be as jittery as someone that hopped up on caffeine should be, so maybe I was just to tired from the race to notice.

Clearly they could be drinking healthier liquids, but if they weren't getting enough hydration, I'd think it would manifest in some noticeable way. My dad would do construction work on a roof top in 95 degree heat all day with barely a thought to drinking anything. I think our parent's generation was made out of tougher stock.
