Nature refresher

My father was right (damn!). Morning air is good for you especially near plants. I live about a block from the botanical gardens and have only been there in the afternoon or evening. Instead of the gym, I walked up the hill through the subtropical trees in the rain while the sun also shone. By the time I got home past the early rush down the escalators, I felt light, clear and ready to fight Goliath.
It's one of the things my dad said I had to do: be refreshed by nature. Actually it was something about negative ions... what were the other must dos?...
