Both of my older siblings and two of my aunts.
My older brother downshifted shortly after I retired, but he was a self-employed dairy farmer who worked pretty much 12 hrs/day, 7 days a week. Now he "only" works a 30 hr/week job, plus some livestock farming in the afternoons/evenings and on weekends.
My older sister is a nurse and likely will be working for another 12-15 years.
One of my still-working aunts is in her late 60s and showing no signs of retiring, even though she would very much like to. The other is in her early 60s and probably still has a ways to go.
