We complain today but not a whole lot of people experience stuff like that. When my Grandpa was a kid he was a bike messenger. There was a granite quarry in the town he grew up in and his job was to use a bicycle and relay the messages from the foreman down to the guys at the bottom of the quarry. He rode a bike carrying paperwork for 10-12 hours a day inside an active quarry for 20 cent an hour at 10 years old. I can hear OSHA screaming even thinking about that now
