Hey man, at least you're honest about it. I think a lot of people who get bored like that end up with self-destructive behaviors, and you're definitely not doing that.
Maybe you need to take a big ol' trip. Go somewhere totally new that scares you... a place that will challenge you and the way you think about the world. Take your wife and explore a new city or country together, or go alone and meet new people, and let them challenge you. I guess that's kinda what ng is saying, too. Get out of your comfort ditch, basically.
But travel is always my answer. It cures just about anything for me. May not be the same as you, but what's the harm in trying it? You're bored, right?
