Hello friend, it is an important issue, many people do not think about it, it is only until they see themselves getting older that they take it into account, but the reality is that we must do something about it while we are young, to see for our future is the best option. There are countries that do not even take you into account after a certain age, so you can not leave your life in the hands of a government, you must work intelligently to have a quality old age. Greetings!
