You're right about one thing. Blood goes where it's needed. Your brain prefers to save your internal organs situated inside of your torso before your appendages, so if there is a choice to be made the torso will always get the better circulation. That is why the torso is pretty easy to keep warm. Probably the easiest part of the whole body.
