Lifespan: What Determines How Long We Live?

Lifespan refers to the length of time that a living organism, such as a human, animal, or plant, is expected to live. It's the duration from birth or germination until death. The lifespan of different species can vary greatly, with some organisms having very short lifespans of just a few days or weeks, while others can live for several decades or even centuries. Factors that can influence lifespan include genetics, environment, lifestyle choices, and access to healthcare.
