"It takes a long time to become young" - Pablo Picasso
It sure did for me.
I started playing video games at my 23, i played my first R.P.G. at 26, The Witcher at my 31 literally changed (saved) my life, and now, at my 39, i find myself younger than ever, because of my interests and hobbies.
No, i won't stop playing video games (oh, my... i can't imagine what will they be in 30 years! ). And i won't stop advertising it to all "serious and mature" people with no interests or hobbies, who are dead and they don't know it.
