it's actually a mother and a son - and my son lost his father nine years ago....I became ill with fibromyalgia after my father's death as I was taking care of my dad, working, shopping, cooking and cleaning and I literally burned myself out....my son became ill after "over doing it" at work = he was only 120 lbs. back then and he was lifting parts that were 100 lbs......he was a heavy machine mechanic = however, that is not what caused his illnesses, just a part.
