Hi Norah!
I agree that walking can serve as a way to escape the hustle and bustle of everyday life. I find walking therapeutic as well, and whenever I feel anxious or overwhelmed, I tend to take a walk to calm me down. It Is crazy to think about how overreliant we are on our cars and how we tend to resort to driving for convenience, like you mentioned when grocery shopping. Although it may be more physically demanding to carry heavy bags of groceries to our apartments, it is definitely worthwhile for both the environmental benefit and our well-being!
I have also been making steps towards walking more everyday. For example, today I had to pick up a course reader from Westwood Village and instead of driving there, I walked. On my walk, I noticed how many cute small businesses and restaurants were around that I had never noticed before!
