Hidden Dangers of Mah-hong

This is a bit curious:

Mah-jong, the popular Chinese domino- like tile game, has been found to cause epileptic seizures, according to research reported in the Hong Kong Medical Journal.

A study released in the August edition of the journal reported 23 cases of mah-jong-induced seizures. Epilepsy sparked by the tile game is a rare condition only recently recognized, the report said.

The study found the affliction can be spurred by critical thinking and decision making. Refraining from playing and even watching the game is the best way for patients to control seizures, the report said.
