Shane O’Mara said: “We know that walking improves your mood, and more than you think it does. Walking might also be a kind of a behavioral inoculant against depression, as well as against the slow, malign changes that mold your personality for the worse because you are sedentary. And walking also brings with it marvelous problem-solving powers. Your creative impulses, fostered by walking, will help knock the problems of life over.”
