Quick question.

Ok based on the logical aspects of why guys like things about girls i have all of them except legs.
Boobs- they hold sữa to feed the child. The thêm sữa the thêm likely their child will survive
Hips- When carrying a child, it would make it easier to carry all of that weight
Beauty & youth- shows that the mother would be able to stay healthy through her life to take care of the child
But what about legs? I do not see anything logical aspect in this :( do bạn have any ideas?
