For the older ones, savings are a must because they can't take any longer risk unless they've got a huge savings that they can attain to lose money by taking risks with investments. It's best for the younger ones to invest at an early stage because they can attain to make mistakes and they can recover eventually, that's why the old ones are good to have with what's left on them if they ever have saved and invested at their young age. And as they grow old, it's best to them to just enjoy the profits they've made to enjoy life.
Yes of course the elderly cannot or should not take risks in their old age considering the financial risks the propensity to make mistakes and the loss of support. Because human productivity is not always the same in every stage of life. But before getting old we all should be interested in investing keeping in mind all the limitations of old age considering the time and opportunity in the right place and saving some money so that in old age we can enjoy the investment dividends.
And because human productivity is not always the same, therefore we must be able to think about investing in our future. After we have invested in the future, of course we will be calmer in living our lives and we will be able to enjoy our old age by relaxing with people who we love, because if we don't think about investment when we are still at a productive age, of course we will continue to work to be able to fulfill the needs we need while we are still alive.
