@johnjohnston @jean Sorry for the tardy reply. I've been off do ing walkabout in my head remembering times and people past and long gone for the last few weeks and have not been checking in as a should.
I think folks are on to something here. I think getting people, especially children, out into the green of nature has a lot of health and immune system benefits. Somehow getting immersed in germs and microbes and natural smells makes us stronger. Just as I've heard that eating local honey is beneficial. Somehow this is all realted.
Aside: @Jean when I first read "forest bathing" from you I had a Twin Peaks flashback "the forest has eyes" or some such. :)
