What I thought would be a little light reading is actually quite fascinating. This study states that one's “coolness” can be boiled down to 6 traits. Agree or disagree? You may agree completely with all the traits, a few, or none at all. 

To me, it is far more individualized as everyone has their own idea of what cool is. For example, in choosing an image to accompany this story I picked one that I thought was cool, but I know not everyone would pick the same.
