What Does It Do to Your Brain?

We live in an era in human history where things are rapidly, rapidly changing. It's easy for people to lose trust in the world around them when they can't rely on what they grew up with to be true any more. The one way i like to put it is, just like those galaxies are changing, if as long as you look at them on long enough time scales,. You know, from day to day we might not think that the world is changing that much. But by the time they get old, yes, we're even week to week.
