A new study has found that 10 percent of kids in Britain are so dumb that they do not know answers to simple questions like what planet they live on.
However, kids are able to recognize faces of famous people like David Beckham, Prince William and Simon Cowell, the survey conducted at CBeebies Land found, the Daily Star reported.
The findings of the study showed that many believe they live on Mars, Saturn or Planet England and think their kidneys are in their heads.
