Many believe that gambling is for young people online as they need thrill and and fun. But I think that even old people can enjoy gambling. There should be any age to retire from gambling at all. One can do this activity and leisure time and thus it does not affect retirement related activities also.
As we age, so does new games are been invented and integrated into gambling if they see that people love it. You don't expect people that were gambling in the 80s, 90s and early 2000s to understand some of the gambling games on casino, they most often than not played what they understand and with time, they don't even have that time they use to like when they were even younger and energetic. However, the age you chose to retire is subjective, some people even quit gambling once they marry if their spouse don't like it, some quit when they give birth to their first child so that the child will not take after them as some of them are bad gamllbler.
If you see gambling as fun and your family don't see anything in it, then I think there is nothing should stop you if you find it fun at any age you are but if you are the type that see gambling as a way to hulse, quit while you are younger, you don't want to be nuisance to your grandchildren. I know of people even when they have older kids, they still go to gambling shop to bet where there children also go to bet. That's very concerning when an elder don't know when to stop.
