Hypothermia is your body getting cold and its reaction. It tries to handle this through various stages. You start with shivering which is your body's way of raising the temperature by use of your muscles. This often includes an increase in heart rate and blood pressure to carry more warmth from your core to your extremities. When that doesn't work, your body starts trying to conserve warmth by slowing down bodily functions such as slower heart rate and pulse. This is to preserve the heat in your core. Your hands and feet will cool off quickly and you'll start to feel lethargic and have a decrease in cognitive ability. Eventually, systems start shutting down leading to death.

Legal word of the day: Fungible - Commercially interchangeable with other property of the same kind. In other words, you put dirty money with clean money, do a few transactions (wash it) and then take out the now clean money. Usually in small amounts. Perhaps the most recent example of this was the Ilya Lichtenstein and Heather Morgan theft of billions of dollars worth of bitcoins back in the 20teens. Might also apply to the current fiasco with FTX.
