Fresh Air will Kill You
Smog, which was once the big attraction of Los Angeles, can now be found all over the country from
Butte, Montana, to New York City, and people are getting so used to polluted air that it is very difficult
for them to breathe anything else.
I was lecturing recently, and one of my stops was Flagstaff, Arizona, which is about 7,000 feet above
sea level. As soon as I got out of the plane, I smelled something peculiar(奇怪的). "What's that smell?" I
asked the man who met me at the plane. "I don't smell anything," he replied.
"There is a definite odor that I am not familiar with," I said.
"Oh, you must be talking about the fresh air. A lot of people come out here who have never smelled
fresh air before." "What's it supposed to do?" I asked suspiciously.
"Nothing. You just breathe it like any other kind of air. It's supposed to be good for your lungs."
"I've heard that story before," I said. "How come if it's air, my eyes aren't watering?"
"Your eyes don't water with fresh air. That's the advantage of it. Saves you a lot in paper tissues."
I looked around and everything appeared crystal-clear. It was a strange sensation and made me feel
very uncomfortable.
My host, sensing this, tried to be assuring. "Please don't worry about it. Tests have proved that you
can breathe fresh air day and night without its doing any harm to the body."
