I'm retiring at 55, and my post-retirement plans involve a lot of sitting around on my fat arse, doing whatever the hell I like with my time, and eventually dying. They do not include any sort of paid work, because I've already done more than enough of that, so the government can do and say what they like, but it won't make the blindest bit of difference to me.
Doing away with the notion that people absolutely must retire completely at pensionable age is a good thing, but there needs to be freedom of choice in every respect. Nobody should feel they must work beyond pension age when they would rather not, and nobody who retires earlier should feel compelled to work either.
