A lot of things go into attractiveness. I don't like women who smoke, but all of the last five women I fell for were smokers. I'm not much for overweight women, but I dated two of them in college. I still haven't sunk so low as to fall for a redhead, but it could happen (heaven forbid).

The thing is that people are a package; there may be something you don't like about the package, but if the other things outweigh it...

Don't think "overweight", think "gestalt".
