Would you want to be frozen, awakened far in the future?

There’s a thin line between being frozen to death and being severely chilled to save your life. For decades, doctors have deliberately cooled the bodies of some patients to temperatures ranging from about 70 to 90 degrees, because the cold slows down or halts the heartbeat and other body processes, allowing more time for surgery. (Outside the operating room, humans typically die when their internal temperature drops below about 75 degrees.)
