There must be 200,000 eggheads for every football star, so why be just another egghead?

And this is coming from an nonathletic nerd who isn't even smart enough to be an egghead.

As other say - Play ball! If he gets injured, then he certainly has a great fallback.

Not only is this data dated, it assumes that people answering the questions are telling the truth.

Perhaps there is a stigma associated with poor people going to McDonald's? Maybe the inference is that "you are so poor, you can ONLY afford McDonald's"? And then when you get to the "rich", they would be reluctant to admit going to such a "low class" and "unhealthy" eatery (even though they love Big Macs just as much as we do).

So, really, the only people who would be truthful are Middle Class.
