It was only a nick but...while I was dripping blood on my brand new shirt, a friend sympathetically chortled “That reminds me. Did you know that there are something like 5 million red blood cells in just one single drop of blood? I wonder how many billions of red blood cells you've just lost!”

This kind of sympathy I can do without but, on the upside, it did spark off two questions...Is this really true about there being over 5 million red blood cells in just one single drop of blood? Somehow it makes me feel sceptically queasy.

But, what if it really is true? Just how many millions/billions/trillions of red blood cells do you reckon the average person has bombing around their entire body?
