    Hi Whistle6 ~ It is blood curdling to know, yes, it can.  I would have never known this had you not asked this question.  I'm glad you did because I looked it up.  I thought it was just a statement to make you think how scary it might be.  I didn't really think it was true!  Thank you for asking!  You taught me something new!!  Bone marrow CAN be frozen as well.  Check out this article I found for you. :)  Thanks for asking!

    Horror Films Really Can Curdle Your Blood

    Reaction to sudden fear might have had an evolutionary benefit, researchers say

    WEDNESDAY, Dec. 16, 2015 (HealthDay News) -- Scary movies really are blood-curdling, researchers report.

    In medieval times, it was believed that extreme fear could "curdle" -- or congeal -- blood.

    Modern-day researchers decided to scientifically test that theory.

    They recruited 24 healthy young adults. Some were assigned to watch a horror movie and then an educational movie a week later, while others watched the same movies in reverse order.

    Within 15 minutes before and after each movie, blood samples were taken from the volunteers and analyzed for clotting activity. Viewers were much more likely to have increased levels of a clotting protein called coagulant factor VII after the horror movie than after the educational movie.

    However, neither movie had any effect on levels of other clot-forming proteins. That suggests that while fear can trigger blood coagulation, it does not lead to the formation of blood clots, according to the researchers at Leiden University in the Netherlands.

    The researchers explained that blood coagulation in response to sudden fear could have been an important evolutionary benefit, because it would prepare the body for blood loss during dangerous situations.

    The study was published in the Dec. 16 holiday issue of the journal BMJ.

  • The clotting against potential injury occurred to me as I was reading.  The caveats at the beginning, especially that "more information" links may be broken is a tad suspicious.  I suspect the phrase has more hyperbole merit than medical reality.
