Well, I saw one post in which you gave a rather unflattering description of your physical self Xev, but you've got one hell of a brain. I wouldn't be surprised if several sciforums users already have crushes on you, and that would be based solely on your personality, or what of it has been seen here. (I believe Nelson was mentioned? Don't worry, I'm only teasing.)
As for the importance of physical appearance, well, it is nice to look at something healthy. Seems to me that our ideas of what is beautiful or not are based on health conditions and breeding potential.
I'm not sure if appearance or personality as factors can completely negate the need for the other. No idea.
