My friend Maksi from Argentina just expressed to me that he needed to get out of Israel over break, perhaps to go to Europe, to "freeze his brains."
It's a new expression which I'm going to translate directly in the future, as well. We'll see if it catches on. Help make it happen.
Necesito /enfriar / un poco/ la cabeza
I need / to freeze/ a little/ my brains
I need to freeze my brains, I need to relax, I need to get out and get some air.
