"For me it was an inconvenience, but for some people it could be life-threatening," said Casey, now an assistant professor in the University of Washington's Department of Environmental and Occupational Health Sciences. "If you had an uncle that had an electric heart pump, basically, his heart wouldn't work without power. You could use a backup battery for eight hours, but after that, if you don't have access to electricity, you have to go to the emergency room. This is a really dangerous situation."
