I find it hard to believe that certain heart patients can't lift anything heavier than a book or a soda can. Is it really that common for the majority of heart patients to risk dying from picking up a dropped pencil? Or is the advice a little extreme to prevent lawsuits? If it's a warning about post surgery, will picking up that empty aluminum can cause stitches in the patient's heart to explode? Or is this just being overly cautious?
