I have an important question: How much coffee does it take to fuel more than 30,000 neuroscientists over a 5 day conference? I feel like here at the annual Society for Neuroscience meeting in Washington, D.C., we must be making a dent in the global coffee supply… My back-of-the-napkin calculations put the daily consumption here at ~ 60,000 cups of coffee per day if everyone drinks 2 cups per day – which would mean ~ 300,000 cups of coffee would be consumed throughout the entire 5 day event. Though, to be fair, I think this is a conservative estimate. As a graduate student, I drank 3-4 cups of coffee a day, and I had colleagues who were much more wired. Here at #SfN14 there are thousands of posters being fueled by highly caffeinated grad students and postdocs, which accounts for many, many lattes and espressos.
