Is it true that 18 year olds are considered babies if they watch only cartoons?

It can be found as babyish to watch ONLY cartoons. Some cartoons are fine, especially if you are with younger children or just having fun reminising (sp? sorry) with your old friends. Only watching cartoons can seem very childish, but mixing in other shows (such as sitcoms, reality shows, movies, etc...) will make things seem a little more normal. Plus, that may be more fun anyway to have diversity :)
