Heavy machine operating, whoo kid you better be a complete straight edge guy. With the money at stake they make sure you're squeaky squeaky. When I was working the docks, the crane dock loaders had weekly drug tests. They made $80k a year, mostly butch dykes and clean cut niggers, the only cleaner cut niggers are bus drivers. You'll never see a sloppy bus driver, and if you do, that guy has drug problems.
