There may be many people who may plan to retire, as they may have jobs. I have always worked as Freelancer, so I do not plan to retire. I have never heard about any kind of freelancer announcing retirement, as there are so many elderly people who are working as freelancers. There are certain kinds of professions where you are not required to "retire". For example, many traders never retire and there are many businessmen who may never need to retire. So, what professions do not require you to retire?
