Extra Income
The amount of people that are wealthy in this world is very low compared to the population as a whole and this means that most people end up retiring without enough funds to enjoy not having to work any more. This is a sad fact, but true. You might not desire to be super rich, but you must a least want to be able to afford some luxuries during your retirement, after all that is what retirement is supposed to be about slowing down and enjoying yourself after many many years of constant working.
