..that rock musicians have a 3 year lifespan has some merit.
Perhaps the same theory can be applied to music writers who, after an agreed time go off and write about something else.
Endless years of free music and exposure to everything must leave even the most rabid music fan a little jaded.
(Not Heppo...of course)
I'm thinking of people like David Marsh and Bob Christgeau here, who have been writing about this stuff for donkeys years now, and whose requirements for what constitutes a great record have been reduced to the Nth degree.
They so often lambast music that I think is great, that I can't really trust them about anything.
10 years for a rock critic, and that's it!
