As an experiment (to determine the effects, if any, on my health, weight and mind), I am maximizing my daily walking and using two different apps to monitor my steps and am battling someone named Inga for first place among the (10) commuters to Vienna using one of the apps. I generally now get off the subway a stop or two early and walk the rest of the way, depending on weather. Or eschew public transport entirely and just walk, depending on available time and distance.
Also, this morning, in order to save the environment, I got dressed in the dark and put on my squeaky shoes by accident.
