I am fortunate to have a grocery store only 3/4 mile from my house. So I walk for groceries.

When I was working at my first engineering job, I owned a car, a
motorcycle and a bicycle. But I walked the mile to work, unless I woke
up late.

Now I ride my three speed even to drop mail at the post office 0.2 miles
away. For me, it's just more fun to ride.

I'm not arguing its fun to ride. I enjoy riding. But for simplicity, its easy to walk 3/4 mile to the store. Just grab my plastic bags and walk out the door. No clothing or shoe change needed. Coming home is a little harder if I buy heavy stuff. My arms get stretched from the weight of the bags. My walk is pretty pleasant when its not winter. Flat. Sidewalk the whole way. Shade from trees for half the distance. And its good exercise.. More exercise than riding the same distance. But its not hard exercise that will improve cardio vascular or strength or anything. Its exercise that gets me off my butt and helps circulation and moves the joints. And I get to breathe fresh air.

The normal marching rate is, and has been since the days of the Roman
Empire, about 3 miles per hour. So a 0.2 mile distance could be walked
in about 4 minutes and a 3/4 mile in 15 minutes. It seems hardly worth
opening the garage door :-)

Are you sure? 3 miles per hour, 20 minutes per 1 mile, is very slow. I easily walk at a pleasant pace to the store 3/4 mile away in at most 10 minutes. Or a bit less. Even carrying heavy bags of groceries home, I still only take about 10 minutes to walk 3/4 mile. That is about 4.5 mph. 50% faster than your official marching rate. I can't imagine any army ever getting anywhere if they only marched 3 miles per hour. It would take them all day to even have a small parade for the top brass.
