For a very long time, we've been extraordinarily interested in the interaction between low temperature and low oxygen. We see that they're connected because we know people who are extremely cold are not getting oxygen to their cells. And yet, they're sometimes alive.
Occasionally, human beings are briefly de-animated, and the stories of people who are briefly de-animated that interest me the most are those having to do with the cold.
Usually when I mention suspended animation, people will flash me the Vulcan sign and laugh.
