I should add that only the last 5 years, I've been living in Vancouver to enjoy milder weather as a non-car resident.

Prior to that I lived several decades in southern Ontario, where winters are like upper New York State,...colder, more snow/slush. During the winters in that province, I did not cycle through snow. It was subway, bus and walking. For a few years, I used to walk almost 1 hr. one way to university every day with at least 4-5 heavy texts in my backpack.

But true, if car-free becomes part of your lifestyle, your whole body becomes adjusted to it.

One good thing being on bus, train or subway, is you can snooze/rest /veg out before or after work. Something you can't do when driving a car.
