I think the main difficulty is to do with how many things we can can give our attention to in the time available. We ignore what we think is unimportant so that we can maximise our attention on what we think is important. That is a pretty good survival strategy - and that is probably why we do it: if our ancestors stopped to admire the butterflies when a sabre-tooth tiger was after them, they didn't live long enough to become our ancestors.

And I recommended Quirkology to Cooran just a couple of days ago ... small world, huh?
