Even though I'm not into anime myself, I don't think there's like a certain age people should just stop enjoying something. It's all down to how the individual handles it. If you're in your 40s, work a minimum wage job, don't have a girlfriend and spend your Saturday nights watching the latest Naruto episode, then maybe it's time to kick the habit. But as long as you're being productive and recognize anime as just a hobby(just like anything else), then there's no reason why you have to put an age limit on it.

Cosplay is a whole other story though. Western cosplay is never cool.
