How long do records last?

I've got 2,000. The first thousand I bought in the last millennium and tended to play once while listening and recording on a high end tape deck and then listened to tapes. Then as I collected the next thousand only listened to them once or twice. While working, if I listened to one a day I was lucky. Now I listen to streaming. So if I listened to mine one time again... I'd have to live to 150 or more. 

I have two comments, Wow, great analysis. This guy thinks like I do and a scientist does. Also, too much time on his hands.

It would be absolutely great if everyone here would be conducting tests of there components and systems with carefully thought out test design and methodical testing. Outstanding job answering one of the many questions in audio.

Also, the blend of listening and measurement is excellent. ASR could be useful if it took some lessons from this guy.
