Animality?

I find quite interesting that we spend a lot of time in cutting our hair and trimming our nails.  We also use special products to make our hair feel softer and look brighter.  We have even invented professionals that we pay to perform these make-up operations on us.  If an alien dropped on the Earth he would probably report that "Humans derive from monkeys but they try to hide it by polishing their hair and making their nails look more gentle."
