According to some studies:

Should every educated person dating have these preferences in mind when considering a potential future marriage partner?
Furthermore, would anyone care to speculate why men who marry younger women tend to live longer while for women it is those who choose to marry a man closest to their age that live longest?
And also, in regards to "high quality" as used in my thread title question, below are some definitions.
High quality man: Handsome, has a good career in a full-time job, smart and well-educated, financially rich, never been in any relationship with opposite sex before (undamaged virgin)
Low quality man: Ugly, has no full-time job, stupid and uneducated, financially poor, has had several relationships with opposite sex already (“emotionally damaged" from investing too much energy in the wrong people and “non-virgin")
High quality woman: Beautiful, has a good career in a full-time job, smart and well-educated, financially rich, never been in a relationship with opposite sex before (undamaged virgin)
Low quality woman: Ugly, has no full-time job, stupid and uneducated, financially poor, has had several relationships with opposite sex already (“emotionally damaged" from investing too much energy in the wrong people and “non-virgin")
