In “the old man and the sea” what does Santiago possess that is not essential to his survival as a fisherman

His only other belongings are kept in his shack. A portrait of Jesus, his beloved wife's belongings, as well as a photo of his wife kept under his shirt because it made him lonely to see it. Other things were mere necessities..... furniture, eating utensils...... the bare minimum. Santiago didn't even own a real pillow. He rolled the newspapers inside of his trousers and made do.
