Maybe combine Grand Theft Auto and education by making the player add up fines or the value of the drugs he just stole...
Diet sodas make your body expect energy. That energy does not arrive.
Hmm. Diet sodas make your body expect energy? Odd. I am a diabetic and have been for the past 35 of my 39 years of existence. I have always consumed diet cola - even when crappy "Tab" was the only choice other than crappy "Diet RIte". My body does not expect anything from a diet cola other than a need to urinate (solely to balance my body's need for water - the base of all cola - and the effect of receiving it). I drink caffeinated and decaffeinated colas. I am neither over weight nor underweight and @ 5'11" my BMI is 24 - "normal" (although my wife says that I could actually stand to gain a few pounds). Statistically, you can correlate anything you want to if you manipulate the scale.
I smell manipulation...
