There are many levels to this. At one end is getting up and moving for a half hour or hour. At the other end is going for a ten-day hike in a part of the planet that has no cell service whatsoever. (Yes, such spaces still exist, but are continually getting smaller — mostly valleys of large mountain ranges.)
This is probably not as big a challenge for me as for many because I find it neither that enjoyable nor that necessary to be jacked in.
