LOL. My legs are tired just reading that! Joking aside, when I first moved to Europe I also had a period where I was constantly converting between ground floor, 1st floor, 2nd floor and 1st floor, 2nd floor, 3rd floor.

I also lived for years in a 3rd (4th) floor walk up with no elevator. Great exercise, especially when carrying groceries.

Now I live on the ground floor. The convenience is great!
