How is blood frozen?
The most common approach to the freeze-preservation of red blood cells in the United States today is accomplished primarily using high concentrations (40\% weight/volume [w/v]) of intracellular glycerol as a cryoprotectant and storage with mechanical refrigeration at -80°C.
Can you really freeze to death?
Your body will freeze in external temperatures a little below the freezing temperature of water, which is about 32 degrees Fahrenheit. However, you can most certainly die before that.
