I know this is a joke, but also I want to see how she is in 6 months. An interruption to your current monotony could be all it takes - once you settle back into routine, will you still be fixed?
Lots of walking to and from places throughout your day is super good for your physical and mental health, all else being equal. Afterall, we're descended from nomads.
There's a balance to be struck, I think most people myself included would benefit from more walking and standing but I remember reading that a study showed people who are on their feet all the time for work had more joint problems. Which isn't surprising.
Even walking the same route is enjoyable. You get to notice the small things - moonrise, birds, people walking the same or opposite way each day
I'm 30 km from my workplace so I cycle, and have a choice of about three paths. When I travel at the same time, same way, I see the same people walking their dogs, jogging, cycling (passing me; me passing them)
