Supposedly:
The idea of a retirement plan dates back centuries to 13 BC when Roman Emperor Caesar Augustus offered Roman legionnaires a retirement package worth roughly 13 times their annual salary. This benefit was available after serving for 20 years in a Roman legion and 5 years in military reserves.
It wasn't universal or for the elderly.
I don't know about the rules of protection for the elderly, but that is likely a thing, where people were obliged to take care of their parents. There was probably a fair amount that broke the law :D
The very nature of human beings, without any law being involved, determines the key moment when we must give up an activity, or change it for a less demanding one.
And a healthy society is built to facilitate people to add value whatever their level, but add value, not only extract.
And I know other younger people, in first class countries, who retired at 60, live very well on the pension they receive.
This depends on the country and what they did prior to 60 I think. Most countries don't pay much in basic retirement, which is why there are so many issues with elderly not being able to take care of themselves financially.
Things are NOT the same in different latitudes,
Yet funnily, people still want equality of result, regardless of the differences in the very people themselves.
