Ananova reports,

Siegfried Lehrl, of the University of Erlangen and Nuremberg in Germany, says sunbathing and relaxation lowers your IQ.

He told Berliner Kurier: “Fourteen days of complete rest can be enough to bring your IQ down by 20 points.”

Mr Lehrl agrees people who work hard all year need some time to relax.

But he says they should avoid getting bored while on holiday, since boredom affects intelligence.

He told the newspaper paper: “Boredom is a warning signal when we feel a lack of mental challenge.”

Mr Lehrl recommends a daily round of backgammon, or taking a book along to the beach to stay smart.

You never saw Chevy Chase reading or playing backgammon in those National Lampoon Vacation movies, did you?

Of course, one wonders if Lehrl hadn’t just returned from a rather lengthy does of sunbathing himself.

    I cannot believe we are still doing this. I thought that was all thrashed out when Kennedy ran for President for crying out loud. Both my parents were Republicans and I can remember them saying that religion was no basis for keeping a man out of public office in *America* (for God’s sake! (easy, Dad…)).

    Yikes!! Should have been the “anti Catholic litmus test” thread. Sorry.
