i agree with this because i think sickness is something that feeling in body, maybe its called addiction like many people said on here and its not good if we continue and we must stop this activity and we should stay away from this.
many people i heard that they can stop gambling but with helping from other people and its really important because other people can give suggestion and advice for that person to stop and distract that person mind to not thinking gambling only and ask to join with other positive activity.
it really depends if the person is actually serious in quitting because if a person is really that addicted, the wont matter what the people around that person is doing. addiction is a sickness that can be caused by excessive gambling and i think one needs to regulate this while he is at the starting stage of gambling as to not succumb to addiction
