Elderlyhood

What's the word for old? ۔

I know this is technically weird, but I wonder if there is a specific term for this stage of life.

I mean there are 3 stages of life: Childhood, Ode and __________.

Other words of work cycle are also welcome! Thanks in advance.

Older

At the very least, the Golden Age is possible.

Elderly, Elderly, Elderly, Elderly, Retired, Retired, Experienced.
