Am I a hoarder, that depends. Many men collect items they think has a purpose or can be reused. I find myself keeping bits of wood, metal, and old tools. Periodically, I have a clear out, but largely to the limited space in this house.
Books and magazines also used to be an issue. Pratchett being my main weakness, followed by biographical books or old car magazines. Again, a system has to be introduced to remove excess literature, before floors began to buckle. l
Otherwise, I have adapted over the years, to a less is more attitude. But being honest, I probably still have a Death Star, hidden in component form, dotted around the house. You can never be too prepared.
