Until now in world's history, whenever we've had a dark age, its been temporary and local. And other parts of the world have been doing fine. And eventually, they help you get out of the dark age.

Isaac AsimovI'm an indoors person. I'm not afraid of the outdoors and I penetrate it easily and cheerfully. However, I must admit I like Central Park better than the wilderness, and I like the canyons of Manhattan better than Central Park, and I like the interior of my apartment better than the canyons of Manhattan, and I like my two rooms better with the shades down at all times than with the shades up. I'm not an agoraphobe at all, but I am a claustrophile, if you see the distinction.
