I can never remember.
I suppose I could look it up right now, seeing as how I am on a computer at this very second. But that just sounds like too much work for a Monday morning when colds and fevers are attacking. And I still haven't recovered from the time Dr. Google told me I had Encephalitis caused by freckles and Menopause that was mostly on my tongue.
The real question is:
What are you supposed to do if you have both a cold and a fever?
Health care is confusing.
