Guess my age, and maybe win a prize...

I always wanted to make a soft drink called "Might Be Grape." And the cans would have question marks on them. Of course, all of the pop would actually be flavored orange, since orange flavoring is cheaper, but more people want grape. That way everyone would keep buying them, trying to get a grape flavored one.
I don't know why, but the subject of this post reminded me of that. Anywhos, I am always surprised when I find out how old or young some of the posters here are. I always just assume most of you are about my age, even though I know it isn't true. And I'm curious how old everyone would guess I am. So here's the contest, guess my age correctly, and you might win a really cool prize! After enough people post, I'll check with my wife to see what the correct answer is.

Dang... orange again!
