The Lifespan of an LP?

I’ve bought some pretty beat up Lps and cleaned them well. When I used a micro line stylus the record sounded pretty darn good. I guess my point is that even if you “wore a record out” there are ways to access more of the groove. 
Those same records sounded siblent and distorted with an elliptical stylus. 

I only have about 300 records.  They have been played quite a bit and I can't tell if the sound has changed.  I play them on this beautiful piece of Americana:  http://www.victor-victrola.com/VIII.htm

Quite fun to listen to the original "Take the A Train" on the Vic and then follow it with a modern digital version on "the big rig"!  Fun is what it's all about.

To the OP:  Some of those records are nearly 100 years old and they still sound pretty crappy but engaging.  Oh yeah, I change styli (needle) frequently and if I see a little corrosion...some warm water and brillo takes care of that. I must have about 150 "needles" and yes they are sharp as a needle. Almost.

I still listen to LP's that I bought 50 years ago. I did damage a few with cheap turntables and cartridges, but with good equipment and care, they may outlast you.

I use Last record preservative. Don't know about vinyl wear but records sound a touch better after treatment. Last has been proven to be a good stuff, I heard.

A long long time.
I stole my dad's collection when I moved out in 1975.  I remember he playing them on a Magnavox phono console in the late 50's.  I played them till 2010ish.  Those records saw a bunch of systems  Always sounded good.  Even when played before or after newer pressings.
