Its simple: if you start younger youll play better. Poker really is a simple game. I won't tell my age or anything but it might be higher or lower or somewhere inbetween those ages listed. Im not biasied in any way towards older or younger but the simple fact is that if you pick up the game at say 15 and play 15 years you will be 100 times better than a 25 year old whos been playing 5 years. Pokers not that hard, its a game, and your life experiences wont make a difference in how you play it.
