I am 75, and when I retired two years ago I started to volunteer to take "elderly people " to Dr app. and run errands for them. I used to color my hair by stopped last October and am now free of trying to hide that gray line in my hair every couple of weeks. I have recently been having pain and weakness in my right hand, Doctor said it is Arthritis..now it starts. I still mow the lawn, clean the pool filter, maintain the flower beds, longarm quilt and babysit some weeks.
Elderly is a state of mind for me, but realistickly speaking...I would be considered by other as elderly just because of my age but not in my behavior.
So like others have said...when one is unable to take care of themselves.....maybe??
