We know how CF bike frames age. CF is not a new material. It does just fine. A decently built CF frame is pretty likely to last longer than your lifetime.
Riding comfort of a bicycle is affected more by other things like tires and proper fit than it is frame material. Also, not all frames of the same material have the same ride feel. How the material is manipulated (thickness, shape, etc.) effects compliance/stiffness.
Repair of a damaged/broken steel frame isn't generally going to be something your LBS can handle. It's going to need to go to someone who specializes in that kind of work, and knows what they are doing. This is exactly the same for CF frames.
