Thanks to Denise from me for asking about what must be a very relevant change in society. Also, thanks to OakDryad for laying out her very logical and interesting thinking.
Reading what OD says, I wonder if we are trying, as a society, to move from one judged by hours and income to one judged by outcomes and achieved added value to our own lives, society and the environment. The "hours and income" society is a left-over from the industrial revolution. It didn't exist for so many people before that. Being bound to a certain workplace is much the same. A great deal of change is going on and it's influencing our later years.
OD compares the fluidity of how parents and carers work, less often just women these days, with "retirement". I think this is a valid comparison but I'm still searching to know what to call this way of life.
In career planning, the descriptions are Portfolio, Portmanteau or Protean career. 'Portfolio' was a traditional, employer directed career path. 'Portmanteau' is a career, where you collect together transferable skills that can be used in very different overarching industries. Protean is a self-directed career, based on using personal values to guide and measure success.
The part of life we are in or are approaching seems to me to be a continuation, or start, of a Protean career. I'm not sure how others would understand you saying "I'm just continuing my values-driven, self-directed life", though and I can't think of one word for it. 
Thanks @DaisyAnne
When the retirement pension was introduced, most people never lived long enough to receive it. For our grandchildren with the ‘100 year life’, retirement may be something referred to in the history books.
I’m trying to think of a description for people like us – probably 50ish to mid-70s-80. The young-olds (yolds?) rather than people like my mum at 90 who is now frailer.
Some people use the term – refire, instead of retire. But do you then say you are refired (sacked twice?). Others say silver-preneurs, which could be fine if you have started a new business, but sounds like a full-on job, not the more balanced life many of us want.
A study colleague of mine uses the term repurposed.
So, ‘Are you retired? No, I’m repurposed.
I quite like that as it opens it up for a follow up question – ‘oh, what do you mean by that?’
