Why does the trash compactor only compact trash sideways? Once ejected into space, wouldn't the flattened, living-room-sized, and extremely solid panes of trash that result from such a primitive, unidirectional trash compactor pose serious hazards for Empire starships in the vicinity?
I have found it helpful to do the stretching exercises my physical therapist recommends. Do some core strengthening exercises, such as the ones highlighted at The Mayo Clinic. By keeping your core strong, your back won't put itself in a position to cause that sciatica pain you are having.
