knowing more than should be known

Is it true that many children or younger kids of this generation know more than they need to know? Yes, I believe this to be very true. I believe many things that we, even I, us teens and children know about many things we should not. Adults, most of them, I think would be scared or maybe even nervous of their child or children knowing more than they need to at such a young or teenage age. This may be nerve wrecking for them because their kids knowing things might lead to them wanting to try or do those things they know about, which in some cases may be negative things. On the other hand, if knowing something positive at a younger age, such as, not drinking, smoking, being under the influence, and more about getting their education, this could be a good lesson and impact on the younger generation in a positive way.
