I'm 35 and sometimes still watch cartoons, is this childish?

Like my post stated, I'm a 35 year-old woman but sometimes still like watching cartoons. For instance I was just listening to Scooby Doo songs. It's interesting.

I guess part of my childish side stayed with me. At times I just like watching clips of cartoon movies (The Land Before Time) or episodes such as Hey Arnold, etc.

Though I don't act childish at work nor when talking to people. I'm in a normal, adult relationship with my boyfriend, where we both talk about our goals and wanting kids soon.
