if you type in your weight, it can calculate how many cups of oh-so-many caffiene-infused beverages it would take to kill ya. the surprising thing is that it would take about 90 cups of coffee to kill me, but 287 cans of cola to do that. and i was thinking coca-cola was so much more evil.
maybe i should lay off the coffee. that one time that i had 10 cups in one sitting, i was 1/9th the way to the grave!
