Its something that you should really be needing up to consider because there would really be no guarantees that you could really be able to retire or finish up it until on the age of 60 on which this is something that will be considered to be the retirement age or much more earlier depending on which country because there are places which does have that less age limit when it comes on getting retired. If you are someone who do last up until the end then its good but factors or risks on being laid of or getting fired would really be still there on which simply means that it will really be just that still depending on how you would really be that handling up yourself on such conditions.
Of course we must always be able to consider our old age in the future and if we can enjoy retirement before the age of 60 it will certainly be better because we have prepared for our old age earlier and if retirement is for a worker in a field that is under contract with a company or certain institutions, then we have to follow the applicable rules, but if we have a business that is running well, of course it will be easier to determine the time to retire and it can even be faster compared to those who work for a company and we will be able to enjoy that retirement period. by relaxing and not thinking about any business.
I do agree that trying to retire earlier than 60 years old makes sense, I am planning on retiring at my 40's for example, that doesn't mean I plan on retiring at 40 exactly, it could be very well 49, that's fine too, just not 50 years old.
Because I spent about 20 years of my life as a kid, and then spend a 30 year period working and basically using my entire life to just be able to afford living, and I just want the last 20 or so years to retiring and resting, but we do not know how long we will live. May I have some health issues tomorrow? Sure, which is why I want to work only until 50, since that means I may live for another day after that, or may live another 30, I rather retire early just in case and make sure I live a decent life after that a bit more.
