Today I caught a snatch on WKSU radio
I found this is 'forest bathing', Shinrin-yoku. The idea is that visiting a forest may calm and relax us, as we breathe the woodland breeze.
It seems intuitively plausible that this might be therapeutic, and there is some scientific evidence of the beneficial effects. I'm biased-pro though, because of my love of trees. Here's a thought I have had many times but only now expressed.
I'd rather breathe my last on a woodland path.
Dying on a hospital corridor would be much horrider.
