ring a ring o roses-not so funny

yesterday i came across an article about plague. one particular fact got my attention. we all know the nursery rhyme "ring a ring o........all fell down".but did you know that the rhyme was about the "black deaths" that struck europe. the deaths were caused by plague. the ring of roses refer to the inflamed rose coloured ring of buboes(buboes-swelling in the armpit and groin).And "all fell down.."signifies the ghastly deaths of these people...........phew...who saw that coming!!!!
