They do. Many Cartoons cater to mature audiences. This is seen in shows like South Park and many anime series.
because adults are older now they might still watch cartoons from time to time
Soon enough
Not at all, cartoons were made by adults, there are even perfectly normal adults who watch nothing but cartoons. Watch what you want
They don't. There are MANY cartoons for adults (though most of them tend to be animes).
well adults watch cartoons maybe to bring out the inner child in them
Cartoons are funny to them,and to some adults
They don't care about their world
There are no known health issues associated with watching cartoons.
p
Because they don't care about their community
cartoons are developed especially for children. The mind of adults is too advanced for any of that. Study shows, the older you get the more bored of cartoons you get.
This we never will know. Watching only cartoons might even be bad.
