I agree with what wise Sabau said:

"The great thing about dating in your 40's as compared to in your teens is that you have so many more years knowledge and patience now than you did then. While the heart may still skip a beat for certain folks, our heads and gut can be followed a bit more than when we were younger and just learning."

I have been divorced from an unhappy loveless marriage now for 11 years, since age 47. The only red flag I see is the sexual aspect. I've had the younger men, the "boy toy" and the "eye candy" also. If you can handle this emotionally, then I say go for itl! I naively thought I could, but found myself attached emotionally to those fellas, resulting in hurt and long periods of recuperation. So enjoy yourself, but just be careful, and take care of YOU!
