Water/hydration
I'm sure I've rambled about this before, but I've never managed to come up with a good answer to the question of "how much water do I need to drink to stay hydrated?" that's founded on decent science.
Points made include:
'8 glasses of water a day' = 2 pints or so. [More is needed in hot weather, I know]
'coffee + tea + other caffeine containing drinks don't count 'cos they're dehydrating' - how does one make up for this? Do they simply 'not count' or does one drink additional water, on top of the 2 pints, to make for them?
'there's lots of water in some fruit and veg' - can this be deducted from the '8 glasses'?
'thirst isn't a reliable indicator of dehydration, by the time you're thirsty you're already 2% dehydrated'
'urine should be pale & copious'
What points am I missing? How do I coordinate them all into a nice, easy to apply strategy for drinking enough water?

no subject
I see no reason not to apply this to human beings. The only thing needed to put into acount is the amount of fluid in the things you eat and drink. I seem to remember something about about thes containing about 1-2 litres depending on the kind of food you eat.
