You have a good point, still, age is not a perfect measure of maturity. Fine, the younger ones must comply with the law and I do not even advise anyone to start gambling until they are over 21 years old regardless of what their country's law states about that. At the same time, many gamblers are only mature in age and not in IQ, so it is always a problem for them. I wonder how these people would be able to manage their emotions when they lose. This is why you see many of them being so frustrated when they in gambling, some will even be addicted and become dangerously desperate about gambling which is not supposed to be.
It's a fact, things are like that, age sometimes does not determine the maturity of a person, I have seen that sometimes there are people of 18-21 years old who have gone through very rough moments in their life and this has made them mature in a great way, they are capable of seeing certain things where a person of 40 or more does not see them, in the case of casinos I see things differently, first I see the confidence they have, the degree of apparent reputation and Above all if we feel comfortable, that's all, it's simple but at the same time it's very important.
I completely agree with you brother, I think I am a good living example of what you said in the first part of your comment.
Coming from a very poor home and being the first born in my family was very tough, I couldnt complete my education due to hardship which is as a result of lack of money, and my dad (God rest his soul) was also struggling to fend for my younger siblings, I dropped from college when things became really hard for my dad, I started doing menial jobs and other forms of hustling just to get money to assist my dad in fending for my younger siblings, I suffered as a young boy, and that built me into the high intelligent man that I am today, not trying to boast, but it still surprises me when I come across some supposedly highly educated people, yet I appear smarter, write better and speak better than them, meanwhile, they are even older than I am - and this explains that indeed, age doesnt always determine one's maturity level.
And coming back to gambling, the more mature a gambler is, the more he or she will enjoy it because, maturity installs in one, sense of responsibility, that is, you feel responsible for all your actions and this makes you conscious of all of your decisions, you are very careful not to make any decision you might end up regretting.
