1. Sex. Banging hotties week after glorious week. An hour or more each time dedicated to your complete satisfaction with a lithe, perky and enthusiastic partner who pulls the occasional outrageously good trick out of her bag. Versus a 50+ cranky Karen. Winner ML/WL

2. Companionship. Your mates; beers, action-oriented hobbies, raucous fun with like-minded brothers. Versus pricey restaurants, ridiculous money for cocktails, the ballet and message-driven movies. Winner. Your mates.

3. Social structure. It's a couples world. Dinner with other couples, cruises, overseas holidays, weekends away. Versus not too much unless you've a lot of single mates. Winner. Marriage/de facto. Arrangements with a few also-single women may work here. But they all seem to want monogamy and a relationship, despite what they initially say. And yeah, sex with a 55+? Jesus.

4. Each other's back. Dealing with health issues, help with decisions, turns with the cooking. Versus no one except your kids, maybe close buddies. Winner. Marriage/de facto.

Hard one. I'd say bang hotties until you're about 70 and then, if anyone will have you, find a companion. Sex is over, slippers look good and you can't drink, surf, fool around like you used to anyway.
Easy to fix the above equation, bro. Just don't marry a 50+ Karen!
The question was about remarrying so it's at least the second time around. You would logically try to get a partner that is much younger than you are to give yourself as much enjoyment in the sex department out of the relationship. Unless you're Jeff Bezos, of course, but that's a different story.

The trick is to find the sweet spot, not too young not too old. I divorced from my ex-wife who was same age as I am (not due to sex problem!), then after a while I got into a defacto relationship with my current partner who's 12 years younger than me. I reckon a wife who is up to 20 years younger is still ok. Any younger and the generational gap would be too much of a strain on the relationship.

Not the only factor of course... Gotta consider if you enjoy living with her, whether or not she's a control freak, etc. But sexual enjoyment is extremely important and if the new relationship does not pass that test, it's not a good idea to commit.
