Easily Distracted People May Have 'Too Much Brain' - Slashdot

I don't even drive anymore because I don't like having to focus on the mundane for long stretches with serious consequences for failure. When in college, my friends and I joked/knew that the faster I drove the safer we were, because screeching around corners on the way to Stinson beach required my full attention; we never crashed. In contrast I have rear-ended countess people, once as a read a newspaper and did not look up in time after getting engaged in a story.
