not just machinery , working with my dad at our auto repair shop when I was a kid , trying to find a vibration in an engine , think it was a late sixties el-camino . standing and leaning over the fender revving up the engine , when -- whammo-- radiator fan blade broke off , non fan clutch , solid steel blade . it winged by my forehead , put barely a scratch on me , flew up , and stuck itself in the metal roof overhead . it stayed up there for years until a reroof , never leaked . we hung a sign from it -- if your careless - you may be headless . to this day I will not stand in the way of rotating things .
