I realized the other day that we have three people at my place of employment that will prove or disprove some common fears. It's very noble of them, really, to subject themselves to such things for science.
One person drinks diet coke. That's all he drinks, as far as I know. I don't believe I've ever seen him drink anything else. Wait, except the grape juice at communion. Therefore, since diet coke seems to be the only fluid he consumes, we will know through him if aspartame is really harmful or not. So far so good.

The second coworker talks on his cell phone quite a bit. If he's not on it, then it's probably ringing. Therefore, if he doesn't get a brain tumor, then you should feel free to talk on your cell phone, as I doubt that any of us (13 year old girls excluded) talk our cell phones quite as much. So far, no tumors. So you have nothing to fear! Except peak minutes. And car wrecks. But not brain tumors.

Seth, another coworker, doesn't eat vegetables, except artichokes, spinach, and large quantities of carrots. If what mother said is true about how you won't grow up healthy and strong if you don't eat all of your veggies, then we'll find out through him. So far, he does seem to get some debilitating illness every six months or so. Perhaps he's proving mama right even now!
