The concept behind the suggestion is hinged on mental faculties of a man. Based on studies, a smart woman will never stop challenging you intellectually; hence a man may keep mental faculties keen forever, according to Business Insider.

The next big thing to consider for a partner is honesty. According to studies, a woman who is more honest tends to be more committed. She can easily get back on track and inform you when you do something wrong.

Another thing to consider is the outlook of a woman. A woman who has a positive outlook would tend to be healthier for you in the long run. Based on a study by psychologist Elaine Hatfield, "negativity can lead to increased heart rate, it impedes our digestion and lowers our concentration."

A woman who laughs at your jokes is another consideration to take. Experts at Westfield State University revealed that a man tends to be conscious more about a partner who thinks they are funny, and such is highly considered by them.

Lastly, a woman who pursues her own goal while supporting yours is a rare find. A recent study conducted suggests that for a relationship to work, a "healthy combination of personal goals and goals you pursue together" is necessary.

By having a woman who possesses such character, there would be less room to for worry. A strong woman with her own goal, would require less validation and will not be that dependent on you.

However, it is good to note that the suggestions above are not exhaustive of itself. There are other things to consider apart what science or reason could suggest. There would be some circumstances that the heart could have its own reason that reason itself could not understand.
