Congrats, EFB!
Your post reminded me that I don't count the value of DH's Defined Benefit Pension in our NW tally. Oh well, I'm not gonna start now, because that would kick me out of this thread, lol!.
In response to Itchyfeet, yes, we're in our fifties (me just barely, and on the wrong end), but we were never high wage earners. I hit $105k exactly once in my career and I was self-employed, so I paid a higher SS tax haircut. For reasons outlined upthread, DH still works. He earns about 80k a year and will probably work for 3 more years, to hit the max healthcare benefit.
We live in a HCOLA, so housing has always been disproportionately high, but owning RE is what made the biggest impact on our NW. Well, that and a dogged determination to RE dating back to my early twenties.
I also believe there are more "oldsters" around than you think. However, once FIRE hits and the shackles of work are removed, people take advantage of their freedom and fly away.
Regarding giving it away, per Mr Griz, I highly recommend it. DH and I joke that we tithe and then some to our community and we're having a blast doing it.
