It is obvious why more people are working past the age of 65 and many are working well into their 70s.
And that's why United Future MP Peter Dunne's is suggesting an incentive to take state superannuation later in life.
His proposal - a varied rate depending on the age at which the entitlement was taken - could solve a number of problems.
Chief among these would be a superannuation payment that allows some quality of life for those who decide to work longer.
Mr Dunne suggests a pension below the superannuation rate could be made available from age 60 for those who wish to retire before they are 65. They would then receive the reduced rate for the rest of their life. People who decided not to pick up the pension until they were 67, or perhaps 70, would receive a higher rate.
The age of entitlement is being raised in developed countries not just to reduce the burden of an ageing population on fewer taxpayers, but also to reflect increasing longevity.
Mr Dunne's practical proposal deserves consideration.
