Tricky Things- Legs
Feb. 12th, 2010 10:39 amI took Fabrizio out the back to kick a ball around. He was up for that, but even more interested in the big stone step between our yard and the path that runs along the back of the houses. He could get up it by himself- no problem- but getting down again was a challenge- and he had to hold my hand or he'd have fallen flat on his face. So what is the secret? What do you have to do with your legs to get safely from A (up here) to B (down there)? We practised the manoeuvre over and over and over.

Slightly less poetically, when we step up, we transfer our body weight onto the raised leg and then use that to lift us. It's a pretty stable movement as we're moving our centre of gravity forwards onto a higher place. When we step down, we're keeping our body weight on the higher leg and lowering the other one to meet the ground - it's far less stable as we're moving our centre of gravity forwards and dropping it at the same time.
Humans are much better at going up than down.

I'm getting the same thrill from climbing (though there, it's me learning how to 'walk' again).

Then you pull it down to centre and forget it in your head.
If you want to teach, you have to pull it back up to your head, while still keeping it in centre.

It's essentially what Donald Rumsfeld was wittering on about when he started talking about "unknown unknowns".
