Scientists have demonstrated that dramatic, positive changes can occur in our lives as a direct result of facing an extreme challenge - whether it's coping with a serious illness, daring to quit smoking, or dealing with depression. Researchers call this 'post-traumatic growth.'

A game is an opportunity to focus our energy, with relentless optimism, at something we’re good at (or getting better at) and enjoy. In other words, gameplay is the direct emotional opposite of depression.

Research shows that when we're under stress or facing a major obstacle, we tend to focus on our weaknesses and what we're afraid of.

Every game we play activates our brain, and it's the same brain we have in real life as we have in the game.

My goal for the next decade is to try to make it as easy to save the world in real life as it is to save the world in online games.

There is so much more knowledge than most people realize about how to maximize the benefits of play and minimize the potential harms.

Games are such a powerful intervention in health and wellness.
