Brian,
Maybe it's a boy thing. I have broken the odd bone falling over things (always sober and never off my high heels) but can't say I have ever been THAT curious.
My brother is a different story... Two broken arms when he jumped (JUMPED) off a two storey building because he was dared to, and then there was the mishap with the lawn mower and bare feet ... He also regularly made his entrance to Mum's house on his mountain bike, down some uneven and curved steps, until the day the entrance was more INTO Mum's house.

The home renovations he began 10 years ago (can't hurry these things) have also provided great dinner table conversation - like the afternoon he spent waiting for someone to come home to haul him out of the bathroom floor which had him trapped to the waist. I'm just glad I knew nothing until afterwards about him moving a support beam (J beam??)by himself that was to support the entire second storey.
He is still with us though - just, and has all of his body parts barring the very tip of his big toe (the lawn mower incident).
