WalletHub has ranked all 50 states in terms of happiness. You'll be "happy" to learn that we live in one of the happiest states in the country! Iowa ranks at number 8 on the list! The research looks at states in terms of emotional & physical well-being; community & Environment and work environment. Hawaii is the happiest place to live in the country. Well, duh. Our neighbor to the North, Minnesota ranked in third place.
Keep going with the Iowa nice. . . i'm no scientist, but i'm sure there is a correlation between being kind and being happy! And boy do people drive through Iowa as if they don't have a care in the world! :-)
