Imagine it had a distinct smell or taste, maybe strawberries, some perfume or some other smell that we usually appreciate. We would just go around and inhale and fill our bodies with good smelling air.
Water, air, and cleanness are the chief articles in my pharmacy. Napoleon said it. Most of us agree, yet we dont know how to appreciate it. We just take it for granted. Air is everything! Air is life!
Get out of town, find a nice quiet place, stand up an just inhale. Feel the fresh air fill up your body and feel the molecules rushing around in your body.... Sweet!
"Fresh air is good if you do not take too much of it; most of the achievements and pleasures of life are in bad air. " Oliver Wendell Holmes :Brainyquotes.com
