Lazy smart people will be the only ones with a 6 pack pretty soon. The misinformed with tons of will power will stay chubby.

How many times have we all seen someone go on an incredibly tough diet (eating bland shitty food) and start running every day while you are just sitting there (on puzzle mats of course) eating bacon and ribs, and deep fried (in tallow of course) stuff whipping your grease hand on your new six pack (:
