I've spent 10 days watching my mother suffer. She lost her balance, falling on her butt. She has 10 bone fractures. Ribs, vertebrae, pelvis. After a couple of days in bed she developed pneumonia. She looked like a tiny bird, her small ribcage quickly rising and falling as she struggled for each breath. Coughing, necessary for pneumonia, was excruciating. Twice she stopped breathing, unable to get any air. Fortunately, she started again.
My mom told me, "Do NOT get yourself in this position. Do the things I never did. I never took vitamins, I never took care of myself."
