Of course people aren't OAPs in their 50s, and even though 65 is officially a pensioner, I think it should be changed to 70, especially as we are expected to work to 67 now.
But I do wish people would stop spouting this nonsense that 61 is actually quite young. It's NOT... As a pp said, you're only 19-20 years away from the average age that women die, only a handful of years away from retirement, and for many people their health will be in decline. (And with some, their health will have started to deteriorate over the past 6-8 years.) Many people this age (early 60s,) will be grandparents, and a few will be great-grandparents!
Saying people in their 60s are still quite young is patronising and condescending. And the type of people saying this are very likely the same ones who say 'this is George, he's 87 years young!' It's utterly cringe! 😖
And I say this as someone who is almost 60 myself, with a 62 year old husband! I'm not quite young, and HE is not quite young, so being so bloody patronising! We are quite old, and there is nothing wrong with that. Why are some people in such denial about ageing? There's nothing wrong with it FFS. Stop talking about it like it's a bad thing. It's a PRIVILEGE that is denied to some people!
