Interesting... I thought free running was the same thing as parkour but wikipedia has separate articles for both... I still don't think free running is all about jumping off from heights and backflips.
Good for you that you're still alive though.
When I was younger, I was always fascinated by heights; I was kinda scared of heights but always wondered about how high I could jump off to live and tell the tale... 15 metres is still way beyond my scale though.
