"(2)  When anyone mentions motorbikes, I have a tendency to wonder whether they have ever owned one.

aawww.. Razib, you have to go down to this topic to enliven your website? Subjecting women to being objectified based on their body parts? Shame on you.

Yes, I have to agree with TG - toughmindedness, which is defined as "facing facts and difficulties with strength and determination; realistic and resolute" is a very attractive quality in a woman. Sensitivity in a woman in the sense that she is aware of & concerned for the feelings & plight of others is attractive. Emotional fragility, however, which makes someone easily hurt, discouraged, insecure, & makes it more difficult for her to get over minor setbacks or effectively deal with the inevitable obstacles & difficulties of life is more like a red flag, especially when looking for a wife & mother for your children. No thank you.  
 
It's notable that when a woman who is a public figure (a la Jackie Kennedy) or just a regular woman who is victimized in some way behaves stoically & shows strength & toughmindededness in the face of tragedy or difficulty, or is considered "scrappy" in her pursuit of some difficult goal & is not easily wounded by verbal attacks on her, she typically comes in for praise, respect, & admiration & her standing is enhanced, especially among men (women seem more sympathetic towards figures like Princess Di, who are known for emotional fragility rather than strength - I think men are more likely to see emotionally fragile women as high-maintenance, over-sensitive, potential pains in the ass).
