You may be right, but in my current circle of friends and family I believe that not to be the case. When I was in my Twenties it seemed like a lot more of the people I knew were cheating. Now, most of us are more involved with church, family and community. With that comes a certain degree of accountability for most of us. I'm in my Fifties now by the way and most of the ones that I do know of or suspect of cheating are Twenty somethings. My wife and I have been together since 1986 and I know for certain that one of us hasn't cheated and I reasonably certain that the other hasn't either.
