> Direction, Time, Distance

I don't really have anything to say about direction or distance, but I believe one's sense of time has a lot to do with which hemisphere of the brain is dominant and what someone is doing at the time.

Keeping track of time is a function of the left hemisphere of the brain, which is responsible for logical thinking (the right hemisphere, of course, being in charge of creative thinking). People who are analytical/logical/intellectual are generally going to have a better sense of time than those who think creatively/emotionally.

But it's not just whether you have a sense of time or not, either. I've noticed that whether or not my sense of time is good has a lot to do with what I'm doing. When I'm engaged in left-brain activity -- most phases of software programming, for example -- I have a pretty good sense of time. On the other hand, when I'm engaged in creative pursuits, I lose track of it easily. In school, I always had a good sense of how much time was left in my math and science classes, but I never knew when my theater, film, or art classes were going to end. There were lots of exceptions to both, actually, but this was a reasonably reliable general rule for me.
