Obviously you're not very careful when handling your CD's, or else
you wouldn't have scratched each and every one of your CD's within
only a year of use.
Of course you can drastically shorten the lifetime of any medium by
abusing it enough. However, this discussion was about the inherent
lifetime of a CD, not about how long a CD can be abused and still be
readable.
So an implicit assumption in this discussion of the lifetime of
CD's was that it should be handled carefully, so it does not
become scratched for instance. It's not particularly difficult,
but it does of course require some care.
