longevity

Longevity refers to how long people or things live. It's about having a long life or lasting for many years.

When we talk about longevity, we often think of it as the opposite of something being short-lived or fleeting. For example, some plants have high longevity because they can stay alive for decades in one place. In medicine, researchers study factors that contribute to human longevity, like a healthy diet and regular exercise. People who live long lives are often seen as having achieved a remarkable level of longevity, especially if they're still going strong well into their 90s or even 100s.
