Don't people have low level symptoms basically all the time? Like if you add up all the times your throat feels a little bit sore, or nose is a little bit stuffed or you cough a few times a day or you have a bit of a headache or you feel a little bit lacking in energy... That should add up to like half a year. So I'm not sure if what you are proposing is realistic.
