Annual Income and Life Expectancy

Annual income is a crucial factor in determining how we live our lives, but it is not the only factor. In addition to our annual income, we also have life expectancy, which plays a significant role in our financial planning and retirement planning.

If we have a high annual income, we can afford to live a luxurious lifestyle, but if we do not plan for our retirement, we may end up with nothing when we reach retirement age. On the other hand, if we have a low annual income, we may need to make sacrifices and live a frugal lifestyle, but if we plan for our retirement, we can enjoy a comfortable and secure retirement.

In addition to planning for our retirement, we should also consider our life expectancy. If we are healthy and active, we may be able to live longer than expected, and if we are not healthy, we may need to adjust our financial planning accordingly. Therefore, it is essential to plan for both our income and life expectancy to ensure a happy and fulfilling life.
