I'm a blue-eyed, blond, cheese eating adult and I like it. That reminds me of something I read about blond, fair people and milk I didn't see it mentioned in the article about vitamin D which is added to milk these days but I don't know if it has any naturally. People with fair skin, blond hair in northern climates helps in the dim sunlight to get enough vitamin D. I also recall reading that people living in a northern climate who have access to large amounts of fish allowed generations of that group of people to retain a darker skin colour since the vitamin D from fish meant people didn't need fair skin to get as much vitamin D from the sun.
