Age does not matter in gambling and I think that if your relationships are more important than gambling then you can left gambling at any age. But if you give more importance to gambling then it become addiction for you and you cannot eliminate this routine.

I don't gamble and will not continue it because I cannot think about such habit which is full of risk.  I think from very initial stage you have to take interest in your children's take care because once they ramble then advising them is not possible.

One cannot think about future correctly because mind of a person can change anytime, may be he understand the things untimely and left it on time and may be he never understands that how intoxicated it is so he will never think about leaving it in any age.
