Countries that have raised the retirement age even further more than a decade ago (such as the UK) have done so while also making the new higher age not apply to boomers. So for example if you are a boomer you get the UK state pension when you turn 65, which most of them have now, but hadn't yet when the law was changed back in 2011. If you are gen x you will have to wait until you're 67, and if you are a millennial or zoomer you will need to wait until you are 68 to get the (probably by that time non-existent) state pension.
