A couple days ago, my daughter had a sofa bed couch delivered to her home, paying extra for delivery and setup. I was there installing a new washer and dryer for her.
Two guys came, one pushed the sofa bed out of the delivery truck, and the second guy lifted it overhead and carried it up the stairs. Not a regular couch, but contained a pullout frame and mattress inside. No way could a woman do this, which is why most delivery people are men. Women can't do many jobs that men can do, and it's true of being consistently on the job and not taking time off. Just a fact.
