This is totally not my field-- medicine-- but totally up my alley-- electronic gaming.  So here goes.  Doctors prescribed playing Nintendo games to cure a boy's blindness in one eye.  And it worked.

The boy had severe lazy eye syndrome in right eye (amblyopia, to be technical), which basically means that eye doesn't track at all.  Says his mother, "he could not identify our faces with his weak eye".

The cure?  "two hours a day playing Mario Kart on a Nintendo DS [... with] a patch over his good eye to make his lazy one work harder."

His "vision had 'improved 250 per cent' in the first week.".

"The consultant added that thousands of youngsters and adults could benefit from a similar treatment."

So should NIntendo be traded as a pharmacological stock now?
