You want that big, heavy sofa moved by yourself, and you try to do it, and you feel your back hurt badly right away. Or you bump and scratch your new table getting it through a tight door. Stuff like this happens a lot when moving. People try to handle heavy furniture on their own. This, of course, stresses them out and can damage their stuff. https://hedge.fachschaft.informatik.uni-kl.de/s/lVUkV7E0F
