Exactly. The definition of life that is taught in school and widely cited is very limited to simply what we traditionally consider alive. But where are fr he lines drawn? Must life be conscious, or at least experience qualia? Does conciousness get more "real" in more complex organisms? (Is a fly just as alive as a horse is?) Why do we consider viruses to be not alive? Are our own bodies' cells alive? In what way? The system is very complicated and we answer is with a hand-waving simple definition.
