I divide the world into:
Those who would be drawn to amphetamines + similar substances (LSD, other speedy things, ADD) (show me EVERYTHING!)
Those who would be drawn to Morphine + similar substances (pot, beer, alcohol) (dull-the-pain, catatonic)
I tend towards the 1st group. But too much of the 1st group (crazy professor, seeing the world at a brighter shade than most) and the world will try to put you into the second category.
