Not close to said age yet. 21 years in. I will probably always work. I'm in medicine and I can work per diem which means no obligation to work so I can work when I want. I anticipate working 2-2.5 days a week starting at age 55. Age 60 drop to 1 shift per week. Keep the mind going, a little extra income, but plenty of time to do what I what with what time is left.
