Actually, this doesn't only apply to money, but to all the assets we own. We have to take care of everything we have, including money and even health. The reason is that when we have a lot of money but we are sick, sooner or later the money we have will run out because we have to go for treatment, while the money we have may not turn over if we are the head of the household.
I see a lot of rich people who have certain illnesses and they don't even enjoy their wealth. They can't even eat like healthy people because they have to avoid certain foods and can only eat certain foods. So in my opinion we have to take care of everything very well.
Generally that's the case, because everyone needs to keep themselves healthy and whatever possessions they have in life and from the example you gave, I've also seen in my place where rich people can't enjoy any food when they suffer from certain diseases. So this made him have to eat food prescribed by the doctor who treated him and that really didn't make him enjoy life because he had to follow the doctor's advice with several restrictions that he had to heed while he was still sick. So maintaining everything we have in this life is a very common thing to do.
