Not at all. I'll be 40 next year and I'm more into Pokemon now than ever. I'm also huge into cartoons, anime, comics, manga, and I own and display many collectibles of all those things. Most of my fashion sense(or lack of 😂 ) are t-shirts and hoodies with prints from all my fav shows, movies and cartoons too. I've pretty much been told my whole life that I should grow up or that I'm too old for this and too old for that. I'll never grow up, and I'll continue to like what I like without a care in the world. Don't worry too much about what others think, just enjoy what you are passionate about and be happy 😊
