I am almost 40.... I spend my free time watching cartoons and animes, old action movies or kung-fu movies. I have RC cars , action figures, video games, airsoft guns.... and I enjoy pencil drawing. I do feel like I am a bit childish. When I was younger, (late teens, early 20's) I was a little ashamed of my hobbies. But one day, I don't know when, I just stopped caring what anyone thought about me.
But even with all of these fun things I have to play with..... my son and daughter still thing I am a dork. Having the support of my wife tho.... thats a huge plus. It makes me feel so much better when shes seems happy I found a kit I want to build, instead of getting mad at me for spending money on a model car.
