My Gran used to say that about herself! She would have been in her early 80s as she died when she was 84. But thinking about it, she had lived through 2 world wars, bombing, loss of her husband, son and most of her relatives so I guess she felt it was true.
It always difficult to know what to say, but if someone says something in sympathy, then you have to accept it for what it is. Most don't want to be insensitive, but are not sufficiently eloquent.
