I think that many times we don't give enough credit to how amazingly lazy our brains are. Whatever they can generalize, they generalize. They don't track images, they track edges and movement (I oversimplify, of course). They can hear garbled speech in a crowded room and somehow figure out what the words are -- even if those aren't the actual words.

To some degree this is good. We don't want to go around testing every chair we come across to make sure it's good to sit in. But it has its downsides as well.




Maybe I don't need to test everything to see if it is a chair, but I definitely test every chair before I sit in it. I learned that I should do that after breaking a few chairs, and a bench.

I'm not even particularly heavy. I'm 180#, which is pretty much spot-on for my height.
