Its an interesting question with clear polarisation of replies - those who would happily keep on working versus those who would not.
You have to reflect what is most important to you. One million sounds a lot, but for perspective it is the level of sensibly invested money likely to be required to cover 10 or more years in a decent care home further down the line.
But having one million in savings gives you choices many others do not have, and its worth having a partner/family conversation that establishes whether you are all leading the life you want, the best life you can and whether that involves work, or not. Just so you are not sleepwalking through every day life thinking it will all be fine, with vague plans for the future.
This thought comes from someone who was recently widowed pretty young, long before official retirement age. Now there is no one to spend our savings with, and money has become less important, relatively, to time spent and memory making. I am very sad we eill not have the opportunity to enjoy spending our savings as we intended, but I am more grateful we had made a prescient decision to retire very early despite having enjoyable high-paid jobs, realising we would be less well-off, but have more time. The right decision for us, as it turned out.
