What you are doing is painting everyone with the same colored brush. I can assure you that not all retired people are working or are worried about their finances. That's the whole point of retirement, as the thread title suggests.
Senior stuff is a whole different topic, the retirement age varies quite a bit. Some retire at 50, some retire at 70, and some never do even though they can. It's just a case by case thing.
Retired means you aren't working anymore, you are just having fun doing things you/yours like to do.
