does coffee has a life span?

Answer 1

All living things have a life span, including a coffee plant.
If you're referring to coffee beans or ground coffee, then I believe you meant to say "shelf-life".

Answer 2

Yes, it will go stale if that's what you mean. Freezing your beans or mixed grounds can help prolong the lifespan. Most coffee will last about three weeks unfrozen. An air tight container helps, too.
