I can remember one of my former neighbours being exactly like that. She was 98 when she died, until she was 97 she used to do the shopping every day for the "old folks" in the retirement home at the other end of the village..... most of them were in their earlier 70's

Mrs. Fisk was one cool lady. It wasn't until after she died I found out she smoked! She didn't want me or my sister picking up "her dirty habit". I used to do her garden for her. A really lovely old lady. Her son was a **** however.... I nearly punched his lights out at the wake!
