i dont know if there had been any change to the amount of years, its possible at some time it was
more than 30 yrs,
the letter they sent me which shows that,,, when i reach my 65th birthday, which is a febuary,, i can retire,,,
but my pension will not start untill june that year , so retirement age itself is not the actual entitlement to pension, it is the date they calculate when you start to recieve it,
