There's a world of space between hoarder and minimalist and I feel pretty comfortable in the middle. I've been working for 40 years now and have bought a lot of stuff that I get a lot of enjoyment out of. My favorite thing in the world is to have time off work with nothing to do and nowhere to go. I think if I were forced to retire today, I'd have no problem spending the rest of my days puttering around my home.
I don't have the hoarding gene, but I might have the hermit gene...
