Might a Public Option Cover Tetris?

A preview of the New York Times Magazine's annual "Year in Ideas" issue is up, and it includes this piece about playing Tetris as a possible "vaccine" for post-traumatic stress disorder.

As a one-time Tetris addict, this fascinates me. I'm currently an online Scrabble addict, as I've also discussed before, and though I wouldn't say I have PTSD, this latest addiction does date to a period when I was going through a very hard time. It sounds reasonable to me that the game soothes me in some way, through some almost paradoxical combination of distraction and intense concentration.
