Hmmm people have goals in their life. Either they are neurotic pleasure or thrill seekers or they want love or they want status or money. Many of those dwarves probably were obessed with mining and riches hence why they didn't get frustrated over not having a girl friend. That is why they didn't conquer others, because they were too busy conquering the mountain. Also notice how many dwarves are bald, that is the testosterone. When males find girl friends and have sex etc their testesterone is lowered. Have a lot of sex and you won't get bald as easily
I wonder what a female dwarf looks like though...
