Yes, I'm necro-posting, such is (un)life. I've just submitted my application for a masters program in critical infrastructure planning and management. It's part of an urban planning department that looks at building enough resilience into water, healthcare, power, and similar systems that they can withstand natural disasters, terrorist attacks, climate change, etc. When people ask what I'll be studying (obviously everyone assumes I'll be accepted, even though it's a stretch for a mid-life career change), I simply say "apocalypse management". They laugh and seem to appreciate the absence of any further explanation.
