Mother nature makes you calm

Have you ever been in a place full of green spaces ?

Some of you had this experience and i believe that they felt so good , whenever we are in the middle of nature we feel so calm and happy , far from any human made stuff, we discover ourselves and know what we have deep in it.
Once we leave the green spaces and move to the human society, we regain that bad mood again, that's why we need to vist such good places from time to time so that we recover what we have destroyed in our natural behaviour.
