If one can not imagine wanting to stop working one must be in good physical and mental health and have found something wonderful to do.
This is a further promise to steal from the old. At any instant there is a certain population in the country, and a certain number of job opportunities. That means there is always a need for the government to fund out of work people. The decision is whether to keep the young on the dole/welfare and force those who have already worked to continue to do so, or whether to allow those who have contributed to reach a rest period and allow the young to make their contribution. The life expectancy has no bearing on it, and is a red herring.
The government is clearly hoping folk will fund not only the unavoidable taxes we all pay, that should pay for pension among other things, but for their own pension on top. Clearly hopnig few actually get to receive it. It is shameful and shows what sort of politicians we get to choose from. Those who can afford not to receive state pension, so are happy to mess up the later lives of others.
