Its basically that gambling is a repetitive thing like say practicing piano but you are getting a risk/reward aspect to it.
So as if you are learning the brain makes the connections stronger and stronger as you reinforce the habit,which makes it that much
more of a issue for you when you try to quit.
Seems to be a lot of people suffering from this due to age and development of the brain at this age.
ehh, piano? you compare gambling with piano? that's a weird one, my friend.
and i don't think age has anything to do with it. people with gambling issue come from variety of age and it has laid its ass here for thousands years.
