Yes I know I post a lot of talks but TED is so full of clever stuff:
Daphne Bavelier: Your brain on video games #TED : http://on.ted.com/mH3l
Felt like sharing another TED talk. I always find the most inspiring things. So apparently video games have positive effects on eyesight and could make you a better driver. Its a shame they only focused on action games but is really interesting food for thought.
