    Was Napolean thinking of astronomers when he talked about "4 o'clock in
    the morning courage"? ;-)

    A brisk walk of a couple of miles is usually sufficient to take the chill away
    and prevent any drastic measure like shivering. Plus it's easier to motivate
    yourself to walk than to do something that requires concentration and
    coordination. And once you're warmed up then everything becomes easier
    and more pleasant. But sometimes getting out of a warm bed just isn't
    natural and isn't right.

    Sometimes the best datum that can be extracted from a series of sights that
    I've taken is the clear message that I need to take better sights.

    Frostbite can be pretty unpleasant but given a choice between -30°C and
    +30°C I think I'd have to take the cold.
