A runner's heart rate

Well I went back to see the doctor again today. I still have not gotten rid of this horrible cough that I have. After running some checks, looking in my ears, nose and down my throat, and listening to my breathing he concluded that I have a sinus infection. Apparently a sinus infection can irritate your throat, especially during the evening, and causes one to have dry coughes. Oh and do dry cough hurt ever so bad. He prescribed some antibiotics and said that I should start feeling better within a matter of days.

The good news is that during my checkup he asked if I ran often. I, of course, responded "Heck Ya, boy!" (alright, I?only said?"yes"). I apparently have a very low rate heart which is common for?runners.
