Water. It’s quite important, isn’t it? We humans are made of around 55%-60% of the stuff, and we need to keep topping it up otherwise we’ll shrivel like a dried prune and expire unpleasantly.If you’re lucky enough to live somewhere you have access to clean drinking water, achieving your daily recommended intake of H2O is fairly straightforward. Grab your favorite receptacle, turn on the tap, and voilà – a cool glass of Adam’s ale.
