I have a wife and two kids. That's one reason I still work (it's probably not a good example for the kids to see a father not working)

More broadly, I'd say if you don't have something to retire to (kids or otherwise), don't.

And if you do have kids, the most profitable thing for your wife to do upon learning you won't be working any longer would be to divorce you, take 50%, impute your income for child support calculation at what you were earning before (so every 5 years you owe your full pre-tax salary). That way their quality of life won't be impacted nearly as much.

So likely at least 8x your pre-tax salary (like 11 or 12x post tax) is gone right off the bat as soon as you retire. So if you are retiring before age 40 basically all of your wealth will vaporize as soon as the mother of your children realizes they can basically take the entire wealth through a mixture of divorce, child support, and alimony and they must act fast before the imputed income calculation drops.
