カジノの制限や禁止についてどう思いますか?

What do you think about age restrictions or bans on casinos and gambling? At what age should people be allowed to gamble, if at all?

Hi, I personally think that from the age of 18 it is in many countries because that is the beginning of adulthood and therefore people should be responsible. 

But on the other hand, I think that they are still just children, so I would move this limit to a higher number, for example 21. 

What do you think ?
