What I have noticed with aged gamblers is that, they do it for Fun, older people tend to get lonely sometimes and in such a moment they can engage in activities that they are used to, for some reason many of them choose gambling as relaxation and engaging in the mental process make them go to casino houses where they can engage the minds regardless of the physical conditions, those older retired citizens are the one's gambling for fun in the real sense of it.
I think I agree with you on this, though I don't really buy the idea of gambling for fun but with your narration i believe that those old folks truly gamble for fun, they don't gamble because of what they may likely gain at the end of the gambling stuff but they just play around to just keep themselves occupied mentally and sometimes they make new friends during this activity, i come to understand that gambling depends on indivudual mindset while gambling, Buddy yea I concur to your conclusions as you said that old folks are mainly the set of individuals gambling for fun sake, you're very correct in this.
