Poo, tears, mucus, pee, saliva, blood, sweat and so on!
A thrilling inventory of the bodily fluids, addressed to small readers. And not so small, because... Do you really know what your bodily fluids are? And how important they are? Did you know that blood passes through your kidneys 300 times a day? And that there are always tears in your eyes? Or that your nose produces up to a litre of mucus every day?
