I broke my left elbow when I was 6 during a summer holiday, because I stumbled on a chair leg in a salon while walking towards my mom and looking at a pretty bridal magazine. That was not fun!
As far as clumsiness, I am clumsy but not so severe... I do trip sometimes and over-cautious just about anything when I walk. Somehow, I develop this fear of falling off the stairs and I'd go down so slow
