Yes you can see what I used to get up to here 
- https://www.youtube.com/watch?v=f6uiaXoZ9mc. It was an amazing way to spend my teen years, very little seriousness and so much fun and adventure! And yes it is incredible how agile and strong the body can get, in that in about 7 years of doing this I only came out with a small fracture in my foot. There were many falls etc but the body does become like a cat. It was interesting having these experiences because a lot of it set the scene for what I discovered later with actualism.
Interestingly enough doing the most dangerous jumps was all about ‘me’ agreeing NOT to get passionately involved, this is when the greatest precision was accomplished. And I specifically remember many times that very bad falls did happen ‘I’ was nowhere to be found in the response, rather it was as if time slowed down and the body reacted with such amazing precision.
Also the way that it is possible to do all this and not get hurt is by developing confidence, in that I would repeat the same jump on ground level until I had the utter confidence that the same outcome would happen over a height. It was not a case of believing that I could make it, I knew that I could make it and furthermore I knew of all the possible “back up plans” was I to fail. This is why it was not actually dangerous in the end, because I developed a razor sharp ability to asses actual risk.
Here is an example of a “bad fall” that somehow ended in no injury at all haha - https://www.youtube.com/watch?v=di_m2bag1xo
