Four-year-old girl with 140 IQ is second youngest Mensa member

One little girl has taken her parents by surprise by proving to be not a little bit smarter than your average four-year-old, but a lot smarter than your average adult.

Alannah George has become the UK's second youngest member of Mensa after achieving an IQ score of 140 - meaning she is officially a genius.

Little Alannah is "obsessed" with words and numbers and taught herself how to read before ever stepping foot in a classroom. The reception class pupil, from Iver in Buckinghamshires, would rather recite the alphabet and times tables, than be singing nursery rhymes.
