What is the average oldest age for a horse?

There's no single "average oldest age" for a horse. Here's why:

* Lifespans vary widely: Horse lifespans depend heavily on factors like breed, health, care, and environment.

* Average vs. Maximum: The average lifespan is generally considered to be around 25-30 years, but some horses live much longer.

* Records: The oldest horse ever recorded lived to be 62 years old.

So, while 25-30 years is a good general estimate, you can't say there's one definitive "average oldest age" for horses.
