Like many here, most of my gear is over a decade old, going back to the early '70s, although I'm not using much of that oldest gear.  Much of my main system is from the late '80s.

Sure do. Most of my McIntosh gear is 17 years old. Power amps- 3 ea MC501’s, a MC402, and a MCP1500 power controller. My Mac CD player just died after 17 years of constant, heavy use and was replaced about four months ago with a new MCT500 CD/SACD Transport. 

Also, my Legacy Audio Whispers and Marquis center speaker are 17 years old. 

All are still looking and sounding like new. 

Yes it's me I'm over 60. Sony integrated amp nakamichi tape technics turntable and cerwin vega speakers. That's ill i could afford in college. Now after the equivalent of 3 ph.d dental,med,6 years of surgical residency in NYC I got some stuff. Enjoy the music and I bought the infinity irs v sound great with electronic crossovers. Alot of old carver stuff. Sae,cal audio tube cd players ect.enjoy the fruits of your hard earned labor and the music

Lots of gear over a decade; ADS L710 speakers from the early 80's (now my L/R  for HT, used daily).  Come to think of it  my AV Receiver is over a decade old - Anthem MRX520.  My CD player is a Marantz that is pretty old, it's a CD6004 from 2012.  I also have a couple of HSU STF-2 Subs that are coming up on 20 years old.  Sometimes I even use my Nuforce iDO DAC with my old iPods (don't laugh!).  And my headphones are both over a decade;  a pair of Grado Labs and a pair of Sennheiser.

Oh yeah, and the guy in the chair.  67 years old.

But the core of my system (Pre, amplifiers, speakers, TT, Streamer/DAC) is under 5 years old.
