Answer:
Depression.
Explanation:
In The Guardian article "It's a Superpower: How Walking Makes Us Healthier, Happier and Brainier", author Amy Fleming discusses how walking is good for one's health. On a discussion with neuroscientist Shane O’Mara, Amy delves into the benefits of walking.
In stanza 5, the author mentioned a study from 2018 that O'Mara cited about how active people are more inclined to have "the positive traits: openness, extraversion, and agreeableness." He continues: "There is substantial data showing that walkers have lower rates of depression, too".
