You may get gamer thumbs doing it, but you’ll look better. You can lose weight playing mindless video games. You have to make sure it’s the right one and Tetris is it.

Basically it’s replacing addiction with distraction. Among study participants with cravings, 24% said they were weakest when playing Tetris. Their need for a Xanax prescription went through the roof.
