Yeah. My Mum's 93 and she's still able to fly from Malta to the UK by herself which is pretty amazing. She was going on cruises up to her mid 80s but the the arthritis got too bad for that. We had hoped to go to take her to Scotland whilst she was visiting, to vist John's Mum, which she really enjoys, but we decided the hours in the car would be too much for her. Las year when she visited we were able to fly and stay longer which made all the difference.
I definitely agree with the slowly falling apart bit. I've found aging to be much harder than I thought it would be but maybe we all feel that way. It constantly surprises me when I discover yet another thing I can't do anymore or have to be careful of.
I understand, I am there too. I've always felt good about the way I have handled things, in the nature of being adaptive and figuring out other ways to do things I want done and the such. Still, for some things, there isn't an easy "other way". I've been fairly good at accepting the changes, but that doesn't mean I don't wish it wasn't like that at times.
