If I like fantasy and Science Fiction, does it make me childish?

Are you a long lost relative? A child that could have been one of my relatives?? I'm over 50. I love and have a passion for fantasy and science fiction. I love all the fantasy movies including the ones by Disney and will not watch anything else that may be on TV at the same time. I love to draw and have son that is into the same things as we are. If you are considered to be "childish and immature, considering {at}I am 24?, What does that make me? I love it and will keep on watching.drawing until all I can see is dirt above me.
