Work is transformative. It gives you a greater chance of a greater income. You can affect your life while you're of working age so you have scope and opportunity. Pensioners do not.
My view is pensioners don't have the one option that people of working age have. They can't really increase their income because they are no longer able to work.
I think one reason for a successful marriage is laughter. I think laughter gets you through the rough moments in a marriage.
