"Life" is like "species": different schools/universities/professors hold different definitions.
Example in this context: a (bio) virus. It has no metabolism, without a host cell it's completely static. The academic world is kinda split when you ask someone in the field whether a virus is a living organism or not. According to one school of thought it's as much alive as a rock.
