Works with my Lifeboat Theory of Love. As a species, we're so driven by the need to procreate that, no matter how tightly the circle is drawn, we're able to adapt our criteria to the options available. I think it's a survival mechanism. No disrespect to your standards, but in my theory, you would eventually pick from ten. Even five.

"think about how many people you dated before you got married"

Who wrote this crap? Date 10 people per person? I've dated at least 50 people and I'm a young person. I'd go mad if I only had 10 to choose from.

My opinion: We are barking up the wrong tree working on sending a colony to space. We need to work on translating human conciousness to a form that can survive space. The vacuum of space is not meant for meat! it is meant for conciousness/information. Once we make the transistion to silicon or some other future substrate that does not require oxygen to survive, space travel becomes trivial. We can transmit ourselves via tiny physical subtrates to almost anywhere in the universe or perhaps even via modulated laser beam slowly or quantum entangelment instantly. We would also become basically immortal allowing us AND our children to see the universe rather than our childrens childrens children. (If they survive the journey...)
