Ill be honest, I’ve seen people (mostly family) that work their ass off to retire and once retiring they basically give up. They don’t take care of themselves, exercise or do anything mentally stimulating. Just watching the news and tv then doing the bare minimum to stay alive.
Because of that their health is very poor and they physically cannot do much and honestly seem to live a pretty miserable life.
They also have lots of chronic pain from working so hard that affects them in retirement. My mom worked in a chair for 12 hours, 60 hours a week and has severe chronic pain from sitting. Being out of shape she can’t stand for very long and chronic pain means she can’t sit very long, she has to spend most of her life in bed.
Personally I believe it’s the best to live life now and have a “soft” retirement, reducing days and hours worked as you age. Human biology is made to work (physically and mentally) and the lack of it degrades our bodies and health.
So It’s technically “never retiring” but personally I think it’s the better option.
