I don't agree. I always see more elderly. people in casinos.
The reason is that new generation spends most of their time in computer and online gambling provides them the facility to gamble from their bedroom. Now there is no need to go outside for gambling and the elders will also never know about their gambling. Thats why the number of youngsters increases day by day. They do not understand what they are doing.
Yes, they can play gambling by secretly without anyone know and if they played for a long time then they have a chance to be addicting in gambling and we need to worry about them. So for people who have teenagers, watching your kids and don't let them in their bedroom for a long time and talk to them or discuss anything so they can open mind for something that is not for them.
The elderly people you see in casinos are more likely to have control over their expenses and have not much use for their money. And the daring of youth most of the time makes them prone to being excessive in things that interest them.
