Here it goes:
Factories weren't easy back in the days. They were packed with workers working as hard as they could to have some food on the table when they got home. I was one of them. Factories were dirty, machinery wasn't as efficient and the environment wasn't very friendly. All we did for hours and hours was stacking, separating boxing, etc. Many people were ill and others exhausted.
Hope it helped,
