Two-year-old Elise Tan-Roberts has become the youngest member of Mensa. With an estimated IQ of 156, Elise is in the top 0.2 per cent of children her age. At 5 months she could talk, she could recognize her written name before she was 1 and she will be ruling the world at 11. Her father says, "Our main aim is to make sure she keeps learning at an advanced pace. We don't want to make her have to dumb down and stop learning just to fit in. But she's still my baby. I just want her to be happy and enjoy herself."
