We at the limbic have watched so many presentations at medical conferences we’ve lost count. So we appreciated stumbling across this graph showing someone’s heart rate at different stages of their presentation (thanks @shitacademicssay). Having also spent hours  squirming in our chair in sympathy for the presenters during the Q&A time we were not at all surprised at the mammoth spike in heart rate caused by that one bizarre question from the most senior person in the room that makes no sense and has absolutely nothing to do with your presentation.
