France Wins the Sleeping Title: Citizens Sleep More than any other Industrialized Nation

No surprise here. They slept through both world wars.

France is the industrialized country where people spend the longest periods sleeping, according to a series of surveys on social habits conducted by the Paris-based Organization for Economic Cooperation & Development.

When they don't sleep or eat, the French hold another OECD record: They have 30 annual days of mandatory paid leave. That compares with 20 in the U.K. and 10 in Japan.

There is no mandatory paid annual leave in the U.S.
