Is it normal for a 45 year old man to enjoy pokémon?

Ok, I am 45 years old. I work hard. I also do a little freelance writing. I have a girlfriend who I love. I have two remarkable children. I take being an adult seriously. I don't like being an adult, but I do take the job seriously. And yet, I play this silly little game. For those who are not familiar with the game, Pokémon is basically a collecting game. There are all these little critters running around and it's the player's job to collect them all. It's not a fast paced game at all. That's what I like about it. I simply can't control those wild action games that look so amazing. I can't play them at all. So I play Pokémon. Is this normal?
