if you're under the lineage of medicine you really do have a gift! Me too, i believe standing under the trees help us because nature releases negative ions that would boost our mood and alleviate stress. Whenever i go hme to where my parents live, i would go the balcony early in the morning to look at the trees around us. Although i live in a busy town where the express way is around the corner, my backyard is full of tree and i just love looking at them because it relaxes me. I did realize my sight becomes clearer too! its amazing how God gave us nature right?
