Have to be honest, thought the article would be about how people who grew up with games are getting older and how they won't change their hobbies just because they become senior citizens. A lot of entertainment habits in places like care homes and among the elderly only exist because they grew up with books and TV instead of games and the internet. When the latter generation grows old, I suspect habits will shift accordingly.
But the effects of games on cognition and what not are interesting to hear about none the less.
