If you can't avoid crowded conditions, if you are near someone coughing
or sneezing turn away , don't inhale until you do and wash your hands
frequently. And use a Neti Pot. Google it.
An ounce of prevention is..... worth a pound of cure.
And tell of friend about this.
A smile would be more than payment.
