A study by doctors in Hong Kong has concluded that epilepsy can be induced by the Chinese tile game of mahjong.
The findings, published in the Hong Kong Medical Journal, were based on 23 cases of people who had suffered mahjong-induced seizures.
The report's four authors, from Hong Kong's Queen Mary Hospital, said the best prevention - and cure - was to avoid playing mahjong.
The study led the doctors to define mahjong epilepsy as a unique syndrome.
Remind me to never get a medical diagnosis from a Hong Kong doctor.
God only knows what you could get from solitaire or dominoes...
