Is it possible to physically change our brain through the power of thought? Professor Richard Davison, a renowned researcher of the human brain, has started up a remarkable experiment: he wants to fundamentally modify the brains of traumatised war veterans and children with ADD through techniques of meditation and yoga, in hopes of making their lives more bearable. But are these techniques, better known as mindfulness, suitable? Are our brains strong enough, or perhaps too strong? And can one man's vision be a turning point in the lives of these people?
