Similar to you, but 'older,' by 2 years.
Balance (and maybe vision) problems, so will have cataract surgery (when I get my act together,) and hope I can avoid surgical treatment for hydrocephalus (
http://en.wikipedia.org/wiki/Hydrocephalus ) which I think I've had symptoms of for YEARS. Walking is my only exercise, and balance is IMPORTANT. Do use a 4-pronged walking stick on uneven ground.
I don't like it when people 'ma'am' me, tho I do understand they're largely being kind. I have 2 new grandsons, one lives nearby, and I hope to help my daughter at home after baby's Dad returns to work next week. Don't want to drive north to see 'other' grandson until after cataract surgery, and hope I don't wait too long with it, but NOT looking forward to dealing with it.
Dad lived until he was 98, so that suggests I may have many years ahead, so I want them to be worth something. WISH I hadn't retired (in '06,) wasn't in my 'plan,' but 'circumstances' intervened. I can pretty easily afford to live more years, and hope, as I've said, doing so is worthy.
Do take care of yourself now.
So, I'm with you.
