We all age differently and this was illustrated so well in a movie I just finished watching. It was on PBS's POV series and it was titled, "The Mole." The story is about an older gentleman hired by a private investigator to spy on the people in an old folks home and learn who was stealing from their client's mother. It was filmed at a real nursing home and all the performers are the actual residents and staff. Our mole is friendly to all and makes it a point to talk with all the residents. There's no script and it's really a commentary on aging and loneliness. After the ending, it is explained how they were able to film the mole and the goings on in that nursing home. See it if you can, it's an eye opener, and is upbeat. It's in Spanish with English subtitles.
After reading Grumpy's post, I had a much better understanding of why that lady said what she did. I'm in my mid 80s and in spite of all my body has gone through, I can do what I want (mostly) and am still sharp of mind. Also, I ride my F3L like a teen who stole it. Some chide me for that, saying I should be more cautious. Why?
