One wants to get rid of future worries for one\'s physical life. And for this, perhaps they save for a lifetime. Some reach those days, some leave the world without touching their savings.

Because each life stage will change according to the time, events and conditions in which it exists.
Unless yesterday\'s formations are renewed, they will not be able to contribute to the needs of new days, just like the economic instruments that are out of circulation.
