I like my work and will keep doing it as for as long as I continue to like it.
I doubt that I will ever stop working completely. I work for myself so I have that option. However, I have been PMR (Pretty Much Retired) for a number of years now. I work, but not as much as I used to.
I have seen people retire and die quickly. Maybe they retired because they were not feeling well or maybe with no more goals they just had no reason to go on living?
