Body piercing controls wheelchair

http://www.bbc.co.uk/news/health-25118896

This news talk about the progress of paralised people.

This progress consists in a movement of a tiny magnet in a tongue piercing which is detected by sensors and coverted into commands which can control a wheelchairs and other gadgets. 

Scientists did a test and saw that twenty three able-bodied people and eleven with tetraplegia could control a wheelchair or a computer. 

My opinion about this news it that it's a good advance because a tretaplegic person could do a lot of things if he or she could move on their own. This is a big advance and if he could control a computer maybe he could work, and have a ''normal life''. Nowadays if he or she could do things it would be one of the biggest things that technolgy can do. In my point of view this novetly could saved a life psychologically, because the person is not left with a useless life as it was before but his life is just a little stagnant.
