Nothing concern gambling with age, the majority of people become addicted to gambling when they get older. I think it is terrible to see people gamble when they are elderly, it doesn't make sense. If someone wants to stop gambling forever, the best age I can see to do so is when they are between the ages of thirty and forty before it should become late. Because that is best time we should be spending with our family, not worrying about gambling. Gambling is still different in old age. If you are wealthy and you still choose to gamble with your own money, no one will think less of you because they will assume you are just having fun. However, if you are poor still continue to gamble when you are older, that is the worst thing you could have done when you were younger. If at all possible, some people should stop gamble at their young age, because it can get more difficult for them as they get older.
When it comes to retiring from gambling, I am not sure there is any general age to quit gambling. There is usually a minimum age for gamblers but I have never seen a maximum age. Retirees will have more time and resources to gamble more. As much as I am healthy and still have some cash to spare, gambling for me is a lifelong journey. It is not just for the money but for the fun it brings to many. When all your children are grown up and the house has become boring, gambling might be a good source of entertainment.
