Possible reason:  All the rubber thingies were made at the same time
(i.e. 11 or so years ago), and have been deteriorating at roughly the
same rate since then.  Rubber has a nasty tendancy to start
disintegrating upon exposure to various substances.  (My knowledge of
this isn't based on anything to do with synths, but from having to
repair my toilet lately :)
