Indefinite lifespan

Indefinite lifespan means that you can live forever or at least a really, really long time - like hundreds or even thousands of years. We know that all living creatures eventually die, but we don't know if it's possible for someone to live forever. Scientists are studying things like medicine and genetics to try to figure out if it's possible for people to have a longer, indefinite lifespan. So far, they haven't found a way to make it happen, but they're still figuring it out!
