Show the answer
70 (answers within ±8 count)
Why
About 70 per cent. The remaining left-handers divide between right-lateralised and bilateral representation. The figure is worth remembering as a corrective: the popular idea that left-handers have "reversed" brains is wrong, most of them are organised like everyone else.
