Rick struggled with depression. He'd lost contact with Suss several years ago and lost his right hand in an accident just over two months ago. He had a prosthetic replacement and decided that he'd try to get back into the groove of life, and one such way his father suggested was by exercising.
Since his missing hand prevented him from doing things such as playing video games, he took up the exercise.
Thus on a day like any other, Rick was working on his bench pressing, still working slowly out of the beginner weights. With a rather loud snapping sound, his prosthetic hand detached from his wrist and he lost control of the barbell, the heavy weighted metal crashing onto his head and knocking him out before it pressed neatly on his throat.
Carol, an experienced gym attendee, heard the loud clang of metal and quickly dropped what she was doing to get the barbell off of him and brought him first aid to attend to the split in his skin.
Thankfully there was no lasting damage, but Rick realized he needed a spotter while exercising, should anymore mechanical failures happen. Carol was more than willing to be his spotter every day from that point forward.
