We had some luck so stopped 'proper jobs' many years early, then worked 'seasons' in both winter and summer to keep us busy so we didn't have time to shop/drink/eat our nest egg away - in what would otherwise would have been lots of free time. My wife now gets a work pension and even though I'm now able to draw on my pension we don't, and instead let it sit there (was rising ever so slightly) so leaving it untapped for the moment (B word worries might change that).
We've both worked with many retirees who had returned to work to curb their spending - and to recharge their holiday/bike/whatever funds, some were on staggering 'full' personal pensions that way exceeded our previous joint incomes, but as they had carried on spending/consuming/wasting at their pre-pension rate had to return to work. Luckily neither of us is spendy/wasteful, but sometimes a call for money can just happen, better to build a really good buffer!
As has been mentioned working life outgoings have to reduce hugely for pension income, OK some of it will be dumping a car/train season passes/business suits/tools/whatever but the ability to just buy stuff on a whim is the biggest change we've seen being the issue.
I wouldn't bank on actually getting the state pension at 67 as that is only the proposed pension age...
Oh and finally I'd make plans for both of you to stop work/reduce days at the same time just for the sake of fairness.
