Time

It's hard to really get a grasp on time. We can see a centuries old building, a 2500 year old tree or a 300 year old turtle and still not get it. There are movies and books to show us the past and the lives of others, but without investing large amounts of our own time we can't even begin to get a grasp on time. When it comes to experience and history we show a remarkable inability to look beyond ourselves.
