People Naturally Walk in Circles
If you're lost in the woods and you feel like you're walking in circles, you probably are.
Without landmarks to guide us, people really do go around and around, found a new study.

I always thought people walk in circles if they're lost because that's the smart thing to do. If you've lost your trail, and you were on it 10 minutes ago, it would be foolish to walk in a straight line for any real distance without finding your trail. In that way, you're only getting further and further from your goal. You need to walk in a circular way to find the trail or some landmark you were on 10 minutes ago. Otherwise you're out of the area you're trying to find very quickly.
Which isn't what little kids do, in my observation. They can walk in a very straight line away from their original spot for miles.
