I'm 47, DW is 45. I do have chronic health issues and will also need a major elective surgery at some point, my wife is in excellent health and hardly ever goes to the doctor. Hard to say how much of my ongoing health issues are related to stress/work but there's only one way to find out

Current accounts:
Taxable: 2.3M - 1.9M is in S&P 500 or Total Market ETFs. ~400K in Total Bond mutual fund
RIRA: 216K - in Total Bond mutual fund
401K: 500K - in Total Bond mutual fund
HSA: 59K- in Wellesley
Cash: 21K
So we're sitting ~3M when I pull out the HSA. We plan on keeping 60/40 AA for our entire retirement.
Overall expenses currently are 69K which I expect to max out around 96K when including ACA insurance, future taxes/cars/electronics/vacations/etc. In our budget we can trim 1-2k/mo of expenses if we really needed to, including a move to a cheaper CoL area in the PNW. That said, my planning uses the 96K number. We have no children and no one we wish to leave a bequest to. We have charities defined which will get whatever is left.
My calculations show we look like we'd be ok (currently at a 3.2% WR), but I'd like to get other opinions.
