technically, water contains some 02, which is technically carcinogenic .... but that's why we have these great self-repair mechanisms in our cells (and the apotosis chains to kill off the ones that went nutters)

I take it you polished off the Rize.

O3, I'm assuming @1 means, as O2 is oxygen. Funny story: stores sold ozone (O3) generators for quite a while to "help repair the ozone layer," you know, until they realized it was carcinogenic. Also, O3 is used by our bodies as a generator of free radicals. Often, preventing and causing cancer are just a matter of dosage.

That's because we're designed to operate using oxygen as fuel.

if we'd grown up on a moon called Pandora, we'd probably be different.

at first glance it looks like the guy with his arm extended is not wearing any pants.

ahhhh...I just had a refreshing one myself. So sorry.

I'm a guy who needs quite the caffeine fix throughout the day, but I dont know that I'd bother posting about my disappointment at being shortchanged at the vending machine. Must be a slow day, huh?

@7: You're a slow day.
