Yes, that's quite funny mate and I definitely agree to the words you are saying because that is true. I also don't feel the difference when I was still 15 years old and even when I'm already 20 years old, I may have a bit of improvement but my priorities and mindset are somehow the same. Everything are almost the same because even a 20 years old can still be called a teenager, not by term but by choices that they made.
Hence why casinos and online casinos are requiring the gamblers to be at least 21 years old and above because by that time, most people do know how to weigh some things.
I agree, by that time people are starting to know each capabilities and interest. We started to develop our brains and as well as they way we think, environment play a big role in our character development. Teens with younger age are very impulsive and easy to be targetted by other people , most of them cannot manager their greed inside and when they can't control it , it will become problem in the future.
I don't know in which countries a 21-year-old begins to be considered an adult personally and I personally see and think that a person who is already 18 years old is the owner of his actions, and that is something that many countries accept, I think that the advantage that a 21-year-old will have is that he will obviously be a more mature person, because he has had new experiences and knows that anything can affect anything, each act has its consequences, in my country he is considered of legal age and is of legal age at 18, no It seems to me a bad idea to think that a person owns their actions, it may be that at 15 years old some still need to live experiences and mature.
I know that in European countries things are different, everyone has their own way of doing things, their rules and since a person can be relevant for any act, personally, I think the ideal age is 18, because at that age you are not a child, you are young but you have to be mature enough to take on any type of act and this is something that must be put into the mind of every young person, you know what is good and what is bad, it is also an age to start earning money and know what to spend and where no
The attitude of young people is currently different, I don't know, but I see that they are very focused on digital, it is not uncommon for them to enter casino and sports betting platforms where they comply with KYC, and still play, so sometimes the freedoms they give in digital can become a double-edged sword, it is for this reason that we as parents, or those who are parents, are always supervising them, with parental control or whatever, but supervising them to avoid any sinister or ugly thing, at least before the age of 18.
Although personally I am a person that even if my children turn 18, I will always continue to protect and advise them, especially when it comes to casinos, sports betting games, I will pass on my way of playing to protect them from addiction problems.
