Satellite navigation systems can stunt your brain, preventing it from developing, according to scientists. They have discovered that taxi drivers have actually grown more brain cells because of all the knowledge they keep in their heads.

When the scientists compared the brains of taxi drivers with those of other drivers, they found the cabbies had more grey matter in the area of the brain associated with memory.

They believe that this part of the brain, the mid-posterior hippocampus, is where black-cab drivers store a mental map of London, including up to 25,000 street names and the location of all the major tourist attractions.
