My mother is 85 and has macular degeneration. The year before my dad died, we agreed that she didn't need to drive anymore. If she had just been driving to church occasionally or to the store, she could probably have driven a lot longer. However, she was making a 40 mile round trip everyday to the nursing home and would often be driving in the rush hour traffic. Not driving was for her safety and others. She had always been a good driver. But, there was no way she was going to stay away from the nursing home every day if she had a car regardless of how dangerous it might be.
Now, however, she has to wait on the charity of others, which is very difficult because she was always extremely independent. It really overwhelms her sometimes. She lives with my little sister in another town. It probably wouldn't be as difficult for her as it is, but my little sister does not communicate. Even if she plans to do something Mother has asked about, she doesn't bother to tell her. So it is terribly frustrating for Mother. It is wonderful that my sister offered to let Mother live there, but sometimes I think it would be better if she lived in a retirement high-rise where she could have access to transportation and other people her age. But, maybe it's more important to be around family for her regardless of the frustrations.
