Same here. The metal I listen to is often older than I am, and I am pretty old.
-Iron Maiden
-Venom
-Testament
-Deicide
-Goat Whore
-Macabre
-Cephalic Carnage
-Behemoth
this list could go on for a while.
I listen to a lot more than death metal though. Lately I have been getting into a lot of Punk Grass groups like Austin Lucas, Drag the River, Lucero and Chuck Regan.
