I don't know TBH. I will probably start cutting down when I'm in my late 20's, early 30's, because I'll more than likely have a wife and maybe a kid. I play about 2 to 3 hours a day, although about half that is late at night, between 10.30 pm and 12.30 am. I definitely won't be playing them when I'm 60, there might be a whole new take on videogames by then, but, saying that, my dad plays pac-man on the computer and plays me at pro evo and he's nearly 60...
