I DO THAT TOO!!!! Omg, I thought I was the only one who flipped magazines backwards! They should do a study on us.
Hmm, something else... I'm an artist and have to eat M&Ms (or any colored candies) in some kind of color order. (although I haven't eaten them in a while- yay me!) This is the routine:
Rainbow- align them into rainbow order then eat one of each color until it's no longer a rainbow
Usually at this point there is something like a traffic light left (red, yellow or orange, and green)
After that there's Christmas left (red and green)
Then red gets eaten first b/c it's yummier (so I think).
I do this subconsciously. I'm not OCD. I'm just weird!
