I m male, age 70, no known pre-existing conditions, non-smoker, no known family history of disease, and exercise frequently. Been experiencing for few (about 3) weeks-- mild intermittent dry cough, throat irritation (mild so far), some indigestion/burping (more recently), fatigue/difficulty sleeping (have had this for years), fatigue (somewhat more than usual), sneezing more than usual, red/bloodshot eyes on doing cardio exercise, particularly if intense (have had this for a while also but eyes appear more bloodshot these days).
