Mensa’s newest member, who is from South Yorkshire, can already count to 200 and name every country in the world at just three years old. Mensa is the largest and oldest high IQ society in the world.   Sherwyn Sarabi’s IQ score of 136 puts him in the top 1% of the world’s population ranked in order of intelligence.

Sherwyn, who has the reading ability of a six year old, began speaking at the age of 10 months and was talking in sentences at 20 months.

By the age of two, he could read, count to 200, recognise and name countries, flags, planets in the solar system, parts of the body and internal organs. His mother, Amanda Sarabi, 36, said that her son loves watching the news.
