Do relationships with older men and younger women work 20 years older?

Yes, to a degree, but the percentage is lower if the man is over 50 plus. As people age they can become more sedate, slower in motion, prefer staying home more than partying like they did in their younger day. It also depends on the woman. If both are the same in personality then it should work. Sometimes it's better to take a risk to see if the relationship works out than to walk away, but always be aware that some women think older men have a stash of money somewhere. That's not saying there aren't a lot of great younger ladies out there for older men.
