My husband is retired and is in his workshop right now repurposing/reconstructing something. I don't know what he's using them for but whatever it is, it'll be really cool. He might be using it for his truck, he's always adding gadgets to it, or something else. I hear grinding, and sometimes the lights in the house dim, so I know he's welding, too. It's important to keep lots of projects on hand for when men retire, they need to be kept busy, at least that's what he says!
