@datarama @liw I forgot to mention no car! I do have three cats, but they don't cost nearly as much as kids.
It will not surprise you that I am on the spectrum too. My late wife was probably borderline.
It was really freeing to me when I wised up and asked the financial advisor. (And was glad I already had one, courtesy of my credit union.) Heartily recommended if available. Fed him my current assets and amounts of the several pensions I had pending, highballed a guess of how much I'd want to spend per month, he plugged the numbers into a program that made reasonable assumptions about inflation and computed I'd be OK until at least age 90. Likely much longer now.
That leaves the problem of boredom/feeling useful--I enjoy my work and that I am helping people who deserve it. (I work at a university.) But I've developed enough other interests that I ought to be OK, and tested it some years back when I got burned out and took several years off working.
In any case I hope you find a comfortabler solution.
