as to the benefits of this actually.
i drink 2 litres of water easily everyday i reckon, i just like it.

It's an entirely arbitrary amount that 'they' (I don't really know who 'they' are, but I don't like them) made up for no real reason.

Probably won't harm you, but it's not 'necessary'.

I hate these stupid RDA figures. 5 fruit-and-veg a day! 38 grams of iron! 19 kilos of calcium! Pah.

seeing as everything you consume has a water content

"the two litres claim is a 1945 US study, which concluded that under normal circumstances most people need around two litres of fluid a day. But this can come from other suitable drinks and from food. For example, a baked potato is 70 percent water."

When I tried to drink 2 litres a day I ended up feeling bloated and rubbish.

and people obtain most fluids from the foods they eat

If I work on sort of 25-30 normal sized glasses a day.

of "fluid".
Even so, 2 litres isn't much and I tend to feel slightly better if I'm well hydrated.
The trick is to not gulp it down, otherwise you just piss it all out. I can never be bothered with drinking slowly.

More just for something to do than the health benefits I think.

it depends on how much you sweat i guess. not that i sweat a lot...
