After suffering a concussion, game designer Jane McGonigal developed a game that can add years to your life by strengthening your level of resilience
In this TED talk Jane McGonical makes and emotional and convincing case on how gaming (setting yourself goals and working towards these (specific actions that are good for you are power-ups), recruiting allies to help you, etc.) can help to achieve your health goals — or recover from an illness or injury — by increasing your personal resilience. An aspect very relevant to healthy aging.
The talk is very inspirational to watch, it is based on a lot of research.
The game she developed for this can be found here:
