There are a few objects I could not live without, such as food, water, and shelter, because they are essential physiological needs that require homeostasis that provide energy, and protect the body.
I would also have a difficult time living without coffee, or a warm blanket for those cold nights. And maybe a dog or cat to keep me company. These objects are not essential m but they would make life more joyous.
