I have just started a new part-time gig in Darwin educating medical students.

It’s pretty easy, really. Eighty per cent of it is just being an enthusiastic lecturer, although the remaining 30% does require some devotion to accuracy.

The teacher’s adage ‘stay two pages ahead of your students’ can’t apply in this billion-webpage world, so the trick is to apply perspective.

I apply this by nodding encouragingly when the student’s diagnostic process mirrors my own, and snorting audibly at any diagnosis I haven’t thought about since med school.
