@ellerbracke Actually, I have not heard that before but I think your own suspicions are probably accurate. That's a lot of sitting too. When I have been sitting that long I always feel it afterward. They recommend getting up and walking every half hour on airplanes but frankly, I am not doing that since they also say there are fewer germs if you take a window seat, so I generally do opt for the window seat. Not catching germs since I am on immunosuppressants is more of a priority for me. I realize the walking is also to avoid clots but I do wear compression stockings when I am flying and I do get up generally every hour or so.
I am sure your knee and hip will be where they were within a couple of more days. Your suitcase doesn't roll? The way I pack that's a necessity.
Sounds like you must be on vacation. Enjoy.
