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.
Of course both old and young people can still enjoy gambling, you know in my country there are still a lot of old people who enjoy gambling more than most of our youth. And the most interesting part is that they don't always feel disappointed whenever the outcome didn't work as they expected, instead they will just accept the defeat and then move on. Sometimes after experiencing lose in gamble they will start planning for other strategy that they can use maybe next time.
