I, like many people, have read manga from my teen years well into my adult life. Many people scoff at manga and comic books as just a pointless and childish hobby. There is nothing that can be learned from them and they serve no purpose other than avoiding reality. Some believe manga to make people antisocial, violent, or somehow emotionally stunted. Those people will just never understand, even if they read manga. It can teach people a lot of things and there are a lot of well-adjusted people who read manga as a hobby.
