If you're someone who offsets the typical HN vocation with outdoor recreation like hiking, cycling, climbing, mountaineering, etc., then consider the weeklong Wilderness First Responder (WFR) course. Much more practically useful than EMT for the majority of time where you don't have an ambulance handy, and you can scratch a similar itch as the author's by doing volunteer Search and Rescue work.
