Your writing is in accord with wisdom acknowledgement that "the man is outdoors animal". On purpose to support the useful recommendation that mitigate the anxiety as common emotional suffering, I would to augment that we live in confrontation with our biologic evolution. The science of biologic evolution teach us that through thousand years the men lived outdoor and only last two hundred years they changed this genuine lifestyle of living. This and many others unnatural psycho-social deviation of current civilization causes many mental disorders among whose, anxiety is most frequent ones. Thus, it goes without saying, that coming back to nature is preferential choice that should decreases our daily sorrow feelings.
