In Italy, our most famous Holocaust survivor, Primo Levi, in his book recounting his days in Auschwitz tells of a man who would spend all his cigarettes on the black market to get some soap and shower every day.
Asked about why, he tells that you not taking care of yourself and your body is what Nazis want to achieve: to turn you in the animal they can exploit to the last drops of blood and sweat.
Taking care of yourself is the first Resistance against Fascism and all those who are against unconditional respect for Humanity.
Take care, Brother.
