Never heard of safe work methods 50 years ago.
The first 30 years I drove 90%of my loads were driver load/unload. 100# boxes of meat, swinging beef, 900 boxes of lettuce, open boxes of semi frozen chicken innards, 140# sacks of coffee beans, dirty cloth diapers, maggot infested cow hides...you name it.
Great way to stay in shape.
