I believe there are cultures of people who dont recognize 2-d images either. Read about it somewhere.

I heard of a study that indicated you could re-set your internal sleep clock by shining light on the back of your knees. What gets me is wondering how they went fishing for that? And the other thing is a distant memory of being a kid, with insomnia, and a restless ache in the back of my knees.

   There are science things Ive heard that I wonder whether they are science or just things people say. You only use a third of your brain, I can accept, but on the condition that its like a warehouse. You could fill it, but couldnt get at anything when you need to.

Eskimos cant watch movies, because their eyes are too quick and they see only a blur. I was told this was utterly wrong, and impossible, but then, that maybe it was true about early movies which were much slower.

Studies show that people like to be as much in everyone elses way as possible, and so they congregate in doorways and passages where others need to pass. This I believe.
