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.
I don't think there should be any age limit for gambling. Once you can control your emotion and be disciplined with your gambling life, then you are good to go. An old person may need to be careful about gambling because of their health condition. This is because if they fail to be disciplined and their gambling life becomes an addict. It may post risk to their health conditions especially for those that are hypertensive.
