Studying the body and brain of gamers

This interest in gamers that is reported on BBC is so weird. It is like gamers are a whole new species that needs to be studied and examined. Anyway, this is also a signal that gaming is becoming an important part of culture. As a gamer, I'm also interested to know what happens when I play games. If there are concrete scientific evidence with regards to the positive benefits to gaming, then gaming won't be seen as a juvenile hobby. But who cares? I love playing my games and no one is gonna stop me.
