Walking is good for our muscles and posture, helps us protect and restore various organs, and can slow down or reverse the aging of our brain. With our mind in motion, we think more creatively, our mood improves, and stress levels decrease. Walking together with others to achieve a common goal also serves as a kind of social bond that has contributed to our survival as a species.

As our lives become increasingly sedentary, we put all of this at risk. We need to start walking again, whether it's climbing a mountain, taking a walk in the park, or simply walking to school and work. We and our societies will change for the better.
