Dan Marvin grew up in the Big Bangs period of the 1980s. These days he can be found in Michigan, once known for its woolly mammoths. He shares hair products with his wife, son and daughter – but not with their two dogs, even though they’re woollier than mammoths. Dan also works in advertising as a creative director and wrote the books IF DINOSAURS HAD HAIR and BUT I DON’T EAT ANTS.
