I just walked back from a place that’s a 30-minute walk or 15-minute subway ride from home.

That is, had I taken the subway, I would have gotten home 15 minutes earlier, but I also would have stood around on the subway for 15 minutes.

So the way I calculate it, I spent 15 minutes getting 30 minutes of exercise.

That’s a win in my book.

Plus, since I don’t have travel time to a gym, I save more time.

Since no medicine has been shown more effective than exercise for mental health, I save trips to doctors, psychologists, and drug stores for help I don’t need.

Plus I fall asleep faster.

And so on.

So I recommend walking when you can.
