I suspect I won't quit my job completely and permanently until I start to lose my faculties. In terms of working conditions, status, remuneration, and, above all, worthwhileness, it ticks all the boxes and although there are lots of other jobs I would like to do in addition, if I had a dozen lives running in parallel, there aren't any other jobs I want to do instead. As soon as it's practical to do so (my work commitment at the moment is driven by the needs of my workplace and is about double what I'd like) I'll drop to three or four 6-hour days a week. I could probably sustain that until I find something I'd rather be doing with that time.
Mad dreams? Well, I plan to take a career break when I turn 55, and my aim, assuming I'm still physically fit enough by then, is to find out what I can achieve as an athlete at the younger end of my age group category if I can "live the life" without work getting in the way of training, eating and resting. The material rewards aren't significant, of course, even if I were to set new world records for my age group, which I won't because I'm mediocre on a good day. But I don't want to look back when I'm 90 and think, "If only I'd given it my best shot when I was 55."
And the rest is just totally sane stuff. Visiting my parents and my adult children more often, and being able to offer to look after grandchildren if they come along (which they may not; I'm cool with that too). Not being too tired to race or provide volunteer support at races at the weekends. Being able to keep my house and garden in better order. Becoming the village busybody. Bikepacking and multi-day hikes with my husband. Getting a cheap low-season hotel package and heading off to the Canary Islands for the whole of the month of January every year. Reading storybooks like I used to. Learning languages, crafts, and practical skills. Organising my time around my body clock.
On reflection, I may not have time to continue to work.
