Tony is a retired mailman. He has lived in New England his whole life and has seen some harsh winters. None, however, was as cold or snowy as one winter a few years ago. First, the temperature dipped to below zero and a snowstorm left 2 feet of snow. Then an ice storm caused lots of broken power lines. That meant Tony had no heat in his house, but he also couldn't leave. The temperature inside dropped to 60° F quite quickly. When his neighbor rang the doorbell to check on him the next day, Tony was confused, and his speech was slurred. He was taken to the emergency room. A doctor examined Tony and warmed him up. When he left the hospital, Tony went to his brother's house until the heat came back on. Turns out he'd had accidental hypothermia.
