Don't. Just don't. You mention stress and health and age as key concerns that require a smart choice -- and yet you're making excuses to sacrifice all three of those things for a little more money, when you already have all the money you need. What the actual fuck?
When a choice seems completely illogical, it is almost always because there is something driving it that is not being acknowledged. IOW, your fixation on the higher-pay job isn't actually about the higher pay -- it's about something else, like the status that job brings you from working for BigName, or the greed that gets tempted by big options/big payday, or the fear of realizing that Job X is the highest you're ever going to get in your career and is that really good enough, or some internalized values of what a man* should be/how he should behave, etc. etc. etc. You need to figure out what is actually driving you to choose a job that you absolutely know is bad for you.
You know the number one rule for success? When you've won, stop playing. You have won the money game. All you need is enough cash to cover living expenses while your 'stache grows a bit more. The "lower"-pay job gives you all that and more; it even pays enough to let your wife walk away from her job if she wants. IMO that's a total win.
You know that saying about how no one on their deathbed ever say they wished they had spent more time at the office? Yeah, it's kind of a crock -- pretty sure there have been a lot of women in particular who over the millennia have wished they could have done something else beyond just cook and clean and take care of kids. But it does bring home that your time is not infinite. Your kids will be out of the house soon. How is it going to feel when they go off to college and you realize that time is done? Are you going finally decide X years from now that it's ok to step back from work, and then realize that the kids are gone and you missed it?
At some point, everyone has to decide how much is enough, and what level of career success/fame/visibility/etc. is good enough. I'm a lawyer; I can literally make more money than I can spend if I want to work my ass off. Instead, I went part-time when my daughter was approaching her senior year of HS, and I liked it so much I stayed part-time. Now my son is in his senior year of HS, and I can't tell you how glad I am that I am here and present for it, both physically and emotionally. Even when he annoys the fuck out of me by interrupting my work to vent about the stupidity of his stats class, there's still a part of me that is smiling inside, because I know for sure that in the not-too-distant future, I'm going to look back and miss having him around for those kinds of little interactions that are so easy to take for granted.
Or to put it more succinctly: my kids have surprised the fuck out of me by turning into cool, interesting people who can have good conversations, who routinely crack me up, and who no longer require me to wipe their asses or drive them everywhere or pay for XYZ. Why in the world would I want to spend less time around them now that they're actually fun?
[Not to mention that the lack of constant childrearing-and-work demands has meant that my sex drive is up, too. Again: why would I want replace that extra energy with more time at the office that will once again leave me so tired all I want to do is crash when I get home? For a little more money? Uhhhh, no thank you.]
*Assumption alert.
