NO!!! Never. There is no age limit for a person to get interested in Anime/Manga. Not in my opinion. Everyone in my house watches anime and whatnot. We all love it. Why should there be a limit on anything as awesome as anime?? :D

Do what makes you happy regardless of age or others opinions

depends on the shows.Anime is not special.Same as other media like movie,Tv ,and novel.

オタク脳だな。大抵の日本人はそれぞれのアニメに対象 年齢あると思ってるよ
幼稚園児向けのアニメ、中学生くらいまでのアニメ、全 年齢対象のアニメといろいろある
大学生にもなって幼稚園児向けのテレビアニメ見てるの はオタクだけ
幼稚園児向けの児童書読んでる大学生、幼稚園児向けの テレビ番組見てる大学生を想像してみろよ
わざと日本語で書いてるから、がんばって解読しろよ

You spoke english in the previous post. What stopping you now, kingdou?? :D

どう答えようがこっちの勝手だろうが
いちいち噛み付くなよ

Oh, there it is again. You know, insulting me or whatever you're doing in your native language isn't right. Just come out and say it like a man. :)

He is, just in his own way :)

There's no age to stop to watch animes; it's ridiculous.
Old people think animes are made to children and idiot adults.
