gambling is so addicting because it is a easy way for people to try and make some fast money. Playing games and being able to win money sounds like music to some peoples ears and they just keep going.
Very nice parable, gambling like music that makes us sleep in the arms of the music.
Gambling will never let you sleep because by doing it you are thrilled feeling mixed emotions and even if you won you don't want to go to sleep because you want some more actions, you can only sleep when you have no money to gamble.
