Apparently, when we fold our arms across our chests it's because we do that when we're in a dangerous situation, and we wish to protect our organs, such as when somebody decides to defenestrate you. This hit me while in my exam and I thought, no, that's not true. I fold my arms when I'm angry, or when I don't want them draped at my sides. I do it to stop my top from sagging and to keep myself warm. I do it to hide what was written on my hand from my dad, I do it to rest against the wall.

Organs are nice things, but most of the time, I don't worry about them. I have ribs to protect my most vital organs, so wouldn't it be more sensible to fold them at my belly, or, for males, even lower down? (That would mean our elbows would have to be in an odd place, so folding hands, not arms, is probably more sensible.) But even the phrase is silly. I fold my arms. No, not really. I fold things once they have been washed so that they can go back into the cupboard neatly. I fold things to keep them un-creased, no matter how silly that sounds.

Now, of course, every time I fold my arms I think of my organs and unfold them, knowing that I don't really care if they get damaged, because then I can blame my ribs and layers of skin and fat and muscle.
