You might think one of the first questions in our screening process is "age range?"
Love, life and joy come from shared goals and personal intimacy, and "age" is rarely a driver of finding "the One". Especially among the elite singles in our database, a lot of the stereotypes fo 40+ and even 50+ just don't hold. Three of our clients in their 50s recently ran the Boston Marathon in a time that would make most runners in the 20s jealous. And yes, one of them was a woman.
Of course, there are some age-related values we have to take into account -- if you are a man interested in having children-of-your-own, a woman in her 40s is probably not a great match. And vice-versa, if you are a woman looking to start a family, there is likely an age among men when that drops off of their goal list.
How about the other direction? Some of the most worldly women I know are in their early 30s, more than a match for a sophisticated 50+ male. Similarly, we have some men in their late 20s in our network for whom the right 40+ woman would be a perfect match.
So back to the original question: is there such a thing as too young/too old in a match? My answer to that is to re-orient yourself around the characteristics you are looking for in a partner, and while junior age or advanced age might negatively correlate with those values, we'll use the values as a filter, not days-on-earth. Richard Branson is 60, do you know many 45 year old women that can keep up with him? Demi Moore and Ashton Kutcher seem to bridge the age gap while Hugh Jackman is happily married to a woman 15 years his senior.
My advice: drop the question and instead re-center on what is going to bring you a lifetime of happiness.
