Someone just argued with me that gambling can be done by kid too.. 
Yes, of course gambling can be done by a kid. It's not that complicated to learn how to do it for a 10 year old. But gambling is definitely not the thing you should introduce to kids because only adult persons have the strength to control themselves, to stop themselves from becoming a gambling addict. In fact as we all know even some adults don't have that strength, let alone kids.
yeah even adults find it hard to have the self control to stop gambling when they're already too hooked in it. that's why i think it would be better to have children educated already at a young age to know the consequences of monetary gambling. it would be easier to make kids understand that than adults who've already tried gambling themselves.
