Vegetarians not so smart?

From the BBC News website this morning:

"Intelligent children are more likely to become vegetarians later in life, a study says. A Southampton University team found those who were vegetarian by 30 had recorded five IQ points more on average at the age of 10... Twenty years after the IQ tests were carried out in 1970, 366 of the participants said they were vegetarian - although more than 100 reported eating either fish or chicken." [my emphasis]

Perhaps they should deduct 10 points from people who think fish and chicken are vegetables.

Video game ratings

With Christmas approaching I have been seeing a lot of video game ads on TV, and apparently the industry has a rating system: E for Everyone, T for Teen, and M for Mature. What I don't understand is, given than most of the ads seem to revolve around rather sad adolescent male fantasies involving guns, cars, and women with extremely improbable anatomies...

...why are none of these games rated I for Immature?
