This roughly 3 hour audiobook scientifically proves what I expected to be true. Florence Williams is a journalist seeking scientific evidence that spending 3 days in nature can promote mental wellness. She participates in 4 nature adventures; one with a group of military veterans, next a group of women trying to heal from addiction and sex trafficking, then with a writer friend who has opposite opinions on this issue, and lastly a solo journey. The scientific evidence is interesting. This book just reinforces my pull to nature as a place that heals my soul and encourages me to do more of what I have been doing. The narration/audio was excellent. The author does a great job narrating and interviews with the participants are a perfect contribution to the audiobook. ( )
