Personally, I think working beyond 67 depends on so many factors.
Saying things like “Oh, I carried on until I was over 70”, isn’t really very helpful - it really depends upon your personal circumstances - physical, emotional and financial.
If you are physically well, working in a role you enjoy that isn’t causing you any stress beyond the ‘normal’ work stresses, then continue for as long as you feel able (not for as long as others think you should).
However, for many people, working beyond the usual retirement age is no easy task, and, quite frankly, not often possible. As some say, despite what our minds might tell us, our physical self tells us otherwise - as we age, we tend to slow down, our energy levels aren’t what they were, our reactions become slower, our bones ache, we tire, we become susceptible to age related ailments. Sometimes, we have to accept that our role as paid employees has to come an end as we can no longer physically do the job.
Yes, keep going if you can, but that is definitely not always possible.
