I'm just glad I don't have your doctor. I hope mine doesn't think
symptoms are all boolean values.
What's in the symptom table is up to the doctor.
Surely the point is that for "high temperature" I need a temperature
value, whereas for "tooth decay" I'll want a tooth number (or whatever
they use). Which brings us back to where we started...
