Aging mother refuses to acknowledge risk of falling

DEAR ABBY: I moved across the country nine years ago to be closer to my parents as they age. They are now in their early to mid-80s. My mother has recently had a few falls. One was bad enough that she had to be taken by ambulance to the ER because she was not able to stand. (I suspect some of her falling is due to having a drink or two at a casino, which affects her balance.)
