If you were stuck outside on a freezing night, would you burn a sacred text to keep warm?

Say you are stuck outside on a cold night with no warm shelter. All the wood around is too wet to light, and you know in a few hours your mind will start slowing from the cold and your limbs will become frostbitten.

Say you also happen to have a stash of sacred texts with you. If you are Christian, they are Bibles, for Muslims Qu’rans, for Buddhists the Therevada, for Jews the Tanakh etc. Would you burn your most sacred books to save yourself coming to harm?

For those who do not value religion highly, what about your national flags?
