I'm sure someone will come along and say, well, I'm 60 and still loving work and my career is on the rise, but speaking for myself I find that the nature of work has changed beyond all recognition since I started work in the 1980s.
As an older person the concept of enjoying working drifts further away from you every year. Work now is a minefield of wellness training, target setting, restrictions, appraisals, new concepts all the time that are a flash in the pan to show off some new manager's 'innovative ideas', presenteeism, zero hours, always being contactable.....until someone puts in a 'you don't have to answer this mail outside of work hours' rule.
Wages being worth less than a decade ago, promotion without incentive, not being able to afford rent or a house even if you work like a demon.
Couple in the loneliness of working from home, poor public transport if you're commuting and not being able to get a GP/hospital appointment if you're sick, it's a wonder any bugger manages to be arsed with work.
Honestly, it's exhausting. I gave up work early (very lucky enough to have a small private pension) because I just could not stand all the bullshit any more.
I took a volunteering job and gave that up because all the work bullshit was being applied even to volunteering).
Not universally, but a lot of work used to be set hours, unions, respect, security, promotions, meaningful pay increase and some level of certainty. It's bloody draining now. Work now is so unappealing. No wonder people are finding ways out - especially older people or young people who have had the Covid years to see that work isn't all.
Maybe I'm just an old duffer, but that's how it seems to me.
