Here's an interesting (and silly) little quiz. I have to wonder what their criteria for "normal" is...

Apparently I'm 45% normal
While some of your behavior is quite normal...
Other things you do are downright strange
You've got a little of your freak going on
But you mostly keep your weirdness to yourself
I did this on a different message board (not weight related) and there was a discussion of the answers. I asked the ones who had high rates of "normality" how they had answered the questions "Would you rather gain 150lbs. or be hit by a truck?", "What do you find harder to control: How much money you spend or your weight?" and "You are more likely to stop wearing something because: its gone out of style or it doesn't fit anymore?"
I think my answers to those questions did me in (after all, they didn't say you get killed in the truck accident!)
