The decline of the community

[LianaThorne]

To add to this: it's currently thought brain development (and by extension, sound decision-making ability) continues into approximately the mid-20s - with some suggestion even the 30s. So even individuals otherwise considered adults may not always be savvy in the things they do. But otherwise, I concur with what you say here.

Piggybacking onto this just cause I felt it useful to add, drug use & alcohol use during teen years also affects brain development and can stunt growth in a way. For example, it affects the ability to control impulses, decision-making skills, the ability to plan and think ahead, etc.
