"I used to think I knew everything, but older you get the more you see other areas. If you could read everything about both sides, you'll pretty much be in the middle again, which is the state you had when you were totally ignorant. So my theory is if you maintain total ignorance - which isn't easy, but I try - you'll be just as far ahead as if you'd spent days and days reading about the whole issue. And you have that much extra time to play Pac-man."
