Granted these people are mentioned in orders as retiring in the sixties but you will find that the large majority, are officers whom have retired from the service early, with an injury caused through work at a young age, not necessarily doing the full 30 yrs service, often only completing a few years service outside their probationary period.
Some do do the full term and live on to a great old age but these are in a very small minority.
It gives the impression that they had a good old go at the pension funds but rarely this is the real picture.
