Years ago in the days of irc, internet relay chat, that is what we did before chat rooms as we now know them, I used to enter a room called 'gay intellectuals' with the sole aim of getting some lively chat happening in an otherwise very dull room. I usually turned the conversation to sex, but in an ever so intellectual way. I would pose theories or sometimes make outrageous statements and stimulate various conversations. Half the people loved my contributions, and the other half hated them. I became bored with it after a while.
But I recall once going off my usual topic and became involved in a conversation about the consumption of drinking water in modern times. I was quickly shot down by intellectuals who knew better than I did. I proposed that we drink too much water and that we are the only animal who drinks water for the sake of it, rather than when we are just thirsty.
For the record, I drink about one litre of Melbourne's best tap water a day. The actual amount depends on the weather, if I have had alcohol the night before and if I think I might need to 'store up' a bit of water. I certainly drink more than what my theory tells me to.
I heard a Sydney medical expert, well specialist of the kidneys I think, whatever they are called, talking on the radio last week. Blow me down, I was right. He simply said, if you are thirsty, drink.
To elaborate, he said that it is the purpose of thirst, to tell you when to drink. A healthy person does not need to drink any more water than enough to satisfy their thirst and there is no benefit in drinking any more. He went on to say that urine should not be clear or even close to clear, but quite yellow.
So there, I was right in what seemed pretty obvious to me. I don't think a litre of water a day is a huge amount and it seems to be about right to satisfy my thirst unless the weather is really hot.
