They keep bumping it up every 5 years with a buffer of some years, so it doesn't affect people close to retirement. If I do the forward calculation of my birth year and month, I will have to work until I am 73 years old in Denmark. But I just cannot fathom doing that.
(Luckily they also just suggested a hard limit on 70 years, but still feels like a lot)
In France, they have been protesting raising the retirement age above 64 years, just for contrast 😅
