I thought McGonigal was such a great speaker, I looked up her old TED Talk; another great talk: Gaming can make a better world.

When game designer Jane McGonigal found herself bedridden and suicidal following a severe concussion, she had a fascinating idea for how to get better. She dove into the scientific research and created the healing game, SuperBetter. In this moving talk, McGonigal explains how a game can boost resilience -- and promises to add 7.5 minutes to your life.

It saved his life. Now he calls on all patients to talk with one another, know their own health data, and make health care better one e-Patient at a time.

Today medical scans produce thousands of images and terabytes of data for a single patient in mere seconds, but how do doctors parse this information and determine what's useful? At TEDxGöteborg, scientific visualization expert Anders Ynnerman shows us sophisticated new tools -- like virtual autopsies -- for analyzing this myriad data, and a glimpse at some sci-fi-sounding medical technologies in development. This talk contains some graphic medical imagery.

Arthritis and injury grind down millions of joints, but few get the best remedy - real biological tissue. Kevin Stone shows a treatment that could sidestep the high costs and donor shortfall of human-to-human transplants with a novel use of animal tissue.

The use of animal tissue will stir up controversy. Compare this to eating meat almost daily though. It seems more humane to use a small amount of animal tissue for fixing ourselves only a few times in our entire lives. We kill/harvest so many animals already, they could use the parts from those animals more wisely.
