What is the age limit for Mount Everest?

Excuse me, but I'm curious to know if there's an age limit for climbing Mount Everest? I've heard of many seasoned climbers taking on this challenge at various stages of their lives, but I'm wondering if there's a formal age restriction in place. It seems like a feat that requires not just physical strength but also mental fortitude, and I'm wondering if there's a cut-off point for when someone might be considered too old to attempt such a grueling climb.
