Now I have some proof. My primary care doctor got sick himself while I was gone, and closed his practice, so he wasn't available to consult on any of what's been going on. But I got my records from his office last week, and confirmed that at my annual checkup in May my heart rate was 76. The year before it was 70. So perhaps the fact that since Africa it rarely gets above 60 and spends an uncomfortable -- in every way -- amount of time in the 40's means that something did indeed happen when I got sick in Rwanda and that whatever it was has affected my heart.
One doctor actually recommended that I see a psychiatrist because I'm probably just anxious about retirement. I am quite experienced with anxiety, and there has been a lot of it recently, but I am not in denial when I say that retiring from my job is not even in the top ten list of things that are currently making me anxious. Boneheaded comments like that are.
