I'm saying this as a tall guy myself. There's research to show that this pairing correlates with easier childbirths and healthier children: intuitively, because the feotus is going to be relatively less cramped in the womb, and get a healthy surplus of resources from the mother.

In the future, I hope that the only women who have to give birth are tall girls with an pregnancy fetish, and ideally we'll use short-guy sperm from a spermbank.
