This is our loose plan too. I don't actually think we need that big a 'stache, we just need to keep our expenses as low as comfortable. I'm just starting to earn decent $, and DH is older than me at ~50. So the plan is for him to downscale work a bit in the next couple of years, I will work full-time for the next 10 or so (I get great vacation time and perks) until I'm 50. He can go to part-time whenever he wants in that time; at 60 (we're 10 yrs apart), he starts drawing social security, to which he can add side-gigs if he wants to stay busy. At that point, I'll likely continue to work at least part-time (which would be 2 days/week, 8 months/yr), but I'll be building a pension, so could keep at full-time if I'm still up for it. Then, given our age difference, we'll see how things play out with health, etc. But between my pension, social security, a paid-off house, a small stache and low expenses, the future looks pretty good. But we're older, so ymmv, of course!
