What services have you received from an area agency on aging? The OP needed an assistant before, during and after a medical procedure. Someone always pops up and says call your department on aging or area agency on aging. Area agencies on aging typically don’t provide anything other than meals on wheels and a room to play games in.
These aren’t the top priorities of the elderly. Aging alone in your own house requires lawn care, house cleaning, laundry, grocery shopping, heating, plumbing and air conditioning maintenance, and bookkeeping. The idea that an area agency on aging will help you with all these items is a myth.
