What type of retirement are you referring to? I am sorry but it is just that the question did not gel up at all.
Age of retirement:
Canada, America, United Kingdom, Asia Pacific, North America and Ukraine have different systems and policies being implemented, solely based on age of retirement.
As of my 2 cents worth, government in Asia has raised the age of retirement and it should be implemented by from the Senate, States of course. Being said much, it is yet to be confirmed due to Time Lag factors; Administrative lag (Approval from all Senate bills to be passed on) and Implementation lag (Affect the entire States requires significant resources & time).
The rest of the procedures must be agreed upon by Discretionary policies (forced decision by government.
Thank-you and do define your question clearer.
