Getting old doesn't mean you won't work anymore. I think I will do something when I retire, a job that I love. If I don't do anything I will quickly get older. This I learned from the old people in the village.
Family finance is difficult to describe. It depends on our own spending. If possible, create food by growing your own vegetables and raising animals like chickens, ducks and pigs.
Always have some money in the bank is the best way to deal with the unexpected.
I would love to do this kind of stuff when I go old, not really after with huge amount of savings but having a small property where I can grow vegetables and fruits together with animals where I can survive my daily needs, it's doable if you have a decent job where you can save some of your salary and start investing with small land property.
along the way, it's your way of thinking about your future and how you would like to live it after you retired.
