Um...just one thing to point out, because I hate false statistics.

The fact that the people who drink diet soda are more likely to be obese does NOT MEAN THAT DIET SODA MAKES YOU OBESE!!

It means that the PEOPLE WHO ARE MORE LIKELY TO DRINK 'DIET' SODA WERE ALREADY OBESE TO BEGIN WITH!!!!

Ugh...I just hate stupid conclusions like that.

It's like this thing from my high school statistics class. 99% of people who have cancer, ate carrots. 90% of people with heart disease, ate carrots. 89% of people with depression, eat carrots on a regular basis.

So...therefore....CARROTS CAUSE CANCER, HEART DISEASE, AND DEPRESSION - right???!!!

Uh...no.
