I put that in the same mental box with worrying about my steel frames rusting away or feeling assured because I can have a tube replaced on my lugged steel frame. I'm sure that all three things happen but, a guy my age probably won't live long enough for it to happen to me. All of my bike frames have always lasted longer than I really wanted them to last. After awhile bicycle frame designs evolve. Rear dropout spacing changes or headset sizes change or I just feel like I want something new.

Incidentally, that comment about aluminum frames losing their "feel" in some period of time - I can remember when exactly the same comment used to be made about steel frames. Back in those days people also said they didn't like aluminum frames because they weren't stiff like a good steel frame. If you live long enough some of these old bikers tales are going to change. Then you get to laugh at the guys who keep repeating them.
