You know what, you're right. How do I know this air business exsists? I may as well stop breathing since I can't prove it's there. While I'm on it, what about this eating malarkey? Can't say I've tried not eating for long periods of time. Who says I'd die anyway? The Man? The Man sucks! I hate the Man! No more soldiers in Iraq! Follow the Kyoto Treaty! Soya-powered everything! Liberal hippy comments!
