First 'major' injury I sustained was when I was four. I was jumping on the bed and I slipped and fell, hitting my head on the bedside table. I needed stitches to close the resulting wound (I think) and I still have a small scar on my forehead from it.

The second one was muscle damage sustained from a heavy fall onto my left arm when I was playing football. That taught me a valuble lesson: never go out the night before an exam
