Don't be fooled by the CPF Life scheme. If you put all your savings into the Enhanced FRS at age 55, you do get more monthly payouts after 65 years old. However, the PAPies had already done their calculation: The amount of monthly payouts can only fully deplete the FRS amount, Enhanced or otherwise, after 12 years at least. So, unless you expect to be able to live beyond 77 years old, otherwise, you'll still have remainder money in your FRS should you leave this world before 77 years old.
Furthermore, between now and 77 years old, if you should encounter a serious illness and will require a large sum of money for treatment, don't expect to get any help from the CPF. In such an unfortunate situation, you will then come to realize that in fact, you do have the money for your treatment, but they are all being held in your FRS and cannot be touched. Sadly it's too late and you can never reverse your decision anymore. The CPF Board will never be sympathetic to you. So, you'll end up dying not because you cannot afford your treatment, but because you are not allowed to have access to your own money for your own treatment. How pathetic and ironic can this be? I wouldn't want to be in such a situation myself.
