I had read, a day or two ago, when this was first posted (presumably by the father) that the kid was perfectly fine and ran off to the swings after this.

Ever ride roller coasters in the rain. Faster. Same with most slides.

I'm in the process of rearing 6 boys, oldest is 7 years. I wouldn't stop recording either. The greatest danger is the boy will now seek greater adrenaline rushes later in life.

Adrenaline rushes aren't dangerous if they're done properly. Personally I'm going to make sure my little boy is exposed to plenty of 'scary' things as he grows up so he can learn about risk and how to assess/handle it properly.

I saw a great documentary about this with Danny MacAskill called Daredevils: Life On The Edge. It looked at adrenaline junkies and investigated why they do what they do. At the end of the program there's a really nice choreographed sequence with MacAskill and various others performing tricks as they descend down the step into an underground station in London, and through the station itself.

The sequence was directed by a hollywood stunt specialist who has worked with all the top guys in big blockbuster movies and he said that the stuntmen and women, far from what most people think, are the least likely people in the world to do something risky. There are two parts to this. Firstly they've learned how to be very good at assessing risk. They understand extremely well what makes something safe or risky. They've had a lot of experience and have learned from it.

Secondly they are very highly skilled. What would be very risky for us to do isn't for them because they have the training to perform safely. We only think what they're doing is dangerous because we ourselves would be very likely to be hurt doing it.

If you insulate a kid from risky experiences you deny them the chance to learn in a controlled environment. It's like teaching a kid to cook. If you look after them really well and provide everything they need and cook them fantastic nutritious meals every day until they leave home they'll love you immensely for it. Then they'll move out, try to look after themselves and end up burning the house down with a pan fire or cut the end of their finger off with a knife or shave the skin off their hand with a grater.

Teach a kid how to use a sharp knife safely and how to sharpen it and keep it keen and they'll be safe for the rest of their life. Kids should be able to use sharp knives, under strict supervision of course, to learn the safe way of doing it. They should be doing 'dangerous' things to learn to do them safely. Part of the learning process is probably going to hurt. They may well get a few cuts before they get their knife skills up to scratch, but if they're in a controlled environment these should be small compared to the injuries that happen when someone with no idea about knives forces a blunt one through something tough.

As for adrenaline sports, the more they fall over the better they learn to balance. If this kid goes on a bit of a bigger slide and gets thrown off in the corners it's going to hurt, but it's not going to kill him. He'll find his limits and respect them more.

I'd rather my kid makes his mistakes while I'm still around to clear up the mess

Such an amazing landing splat. Needs to be looped about 7 times.

For some reason I imagine you're Goku, forever creating powerful super saiyen children to dominate the universe. Pair them off, have them fuison dance, then have the fused pairs fusion dance, and then finally you fusion dance with the super fused saiyen entity and become -- I don't know. Scanners don't work so well after that.

The sheer numerical value is pointless and really, why? Why do you keep having these saiyen children? Don't you realize they will destroy the universe?!?!?!
