I managed it through savings and doing materially well out of a divorce, and due to a bit of luck (although I'm a firm believer that you make your own luck) I ended up owning 2 houses outright so have a steady rental 8ncome. I could have no pension at all and still - barely - have stopped when I did.
Think about it. I've never had car finance, so that's 3 and a half grand or more I've saved, each and every single year of my adult life - if we assume 300 sovs a month is fairly typical, that is £125,000 that I haven't spent that the typical working car driving adult has chucked away. That's gone into my bank.
Multiply that by all the other things people spend their money on, and suddenly in my early 40's I find that I have a lot, and I mean a lot, of liquidity. That gave me something to think about sat in my sun lounger on the patio for 2 weeks every year. Think about that next time you sign up for a new car, holiday, mobile phone contract, gym membership, etc, etc. The choice is yours and no one elses.
It's a lifetime of undisciplined spending habits that delays retirement for a significant number of people, but they're too close to the problem to see it and blame the fact that they weren't in the forces or uniform services for having to work so late in life instead. Well I've news for them - they're simply wrong.
