When I was in high school, I was in a car accident I luckily walked away from, yet I was still haunted by flashbacks hours later. Turns out this is a symptom of post-traumatic stress disorder, or PTSD. If only I had known about the medicinal wonders of Tetris.
Oxford University researchers who apparently have a lot of free time on their hands are saying the video game Tetris can help fight PTSD and memories of traumatic incidents if played shortly afterward. It could be used to help people involved in accidents (assuming they can use their fingers) and soldiers returning from war (same caveat).
We firmly believe there is another, older way of dealing with traumatic incidents.
