I could never, ever have a relationship with a shorter guy. It's the one appearance-based deal-breaker in my book. One of my first boyfriends was quite a bit shorter, and I was so uncomfortable with it that I eventually broke up with him even though I really liked him. Shallow, I know, but I am quite big (not tall, 5'5 1/2", but big) and I hate feeling like a lumbering elephant, which I do standing next to short, slender men. DH is about 6' and hefty, which I love.
I seem to remember hearing something about florescent lights making people grow taller....anyone else hear that?
