unlikely cure for psychological trauma

In the past few years i have heard how video games corrupt minds, waste time, etc.
Well a recent study at Oxford Unicersity hypothesized that playing the video game Tetris after witnessing violence could get cognitive resources the brain normally needs to form memories.

The journal PLoS One confirmed the finding stating " Tetris acted like a 'cognitive vaccine' against traumatic memory."

I'll make sure that i start carying a gameboy around with Tetris so if i ever experience psychological trauma i can get rid of it by playing my game.
