Dr. Nortin M. Hadler is a professor of medicine and microbiology/immunology at the University of North Carolina at Chapel Hill, and attending rheumatologist at the University of North Carolina Hospitals in Chapel Hill. He also sounds in this ABC News op-ed a lot like my father:

To be well is not the same as to feel well.
Being well requires some sense of invincibility. No one is spared symptoms for long.
It’s abnormal to go one year without upper respiratory symptoms or pain.
Lurking in our future are heartache and heartburn, shoulder and knee pain, headache, rashes and skipped heartbeats — not to mention bothersome fatigue, sore muscles, bowel irregularity, insomnia and so much else to challenge our sense of well-being.
Nearly all of these predicaments can go away as mysteriously as they come about. To be well requires the wherewithal to cope with these ailments for as long as that takes — and it can take weeks. [. . .]

If so, can it be treated? If not, can we discern why I can’t cope with this episode?”
