[quote=flyer]. . . One of our neighbors is in his late 60’s–holds multiple patents–and is still working on others. We honestly don’t know anyone who is completely “retired,” regardless of their age or financial status.[/quote]I’ve got a relative like this and I always visit his tool and die shop when I’m in town. He’s “semi-retired” but keeps extremely busy filling “special orders” for local businesses. He’s invented so many interesting things and also holds multiple patents … which seem to take a l-o-o-ong time to wind their way through the “system.”
