Mostly its nobody's business but the person concerned but extreme addiction may be an indication of neuronepaenia. :(
What problems arise from an adult watching just cartoons?
There's no problem , it's fine. I love cartoons so it's fine cos I said so.
The only problem I see is not being able to discuss whatever show is popular with friends and coworkers. And if you don't watch the news at all you maybe lacking in current events, unless you are actually reading the articles on the internet and not just the headlines which are most often misleading.
The only problem I can see is perhaps having a useful and clear understanding of many of the moral dilemmas that adults face in life.
And let me assure you, while you may think that is an advantage, it is much easier to be just "one of the good-ole boys."
Only watching any "genre" of anything is very limiting .. No matter what it is. Much better to have more "well-rounded" interests.
I have been watching cartoons most of my adult life..... And I seem to be normal. I think! LOL!
i can watch bugs bunny and road runner and taz all day its better than the crap on now
Depends on how they spend the rest of their time.
I spend maybe 1 hour a night watch television . . The rest of the time is . . Shall we say, more constructive . . . So if I spend that time just watching cartoons . . . So what.
When I binged watch "Attack on Titan" that was the only thing I watched for about a week . . . No big deal.
