I just realized my world is shrinking and never thought it would happen to me. So 4 years ago while power walking my big dog the sidewalk was uneven and I tripped and had a head injury. So I slowed down. Then my husband was gone and I fell outside on the ice when taking the dogs to pee which was at night and very cold. What if I had hit my head and been out there all night? Luckily I only broke my wrist and was able to get the dogs inside.
