How to Recognize That Your Girlfriend is Your Future Wife

To be 100% confident in your choice,  rely not only on your intuition.
1) Simple Arithmetic 
It's not the most romantic way to think about it, but your friend is a random variable in the equation of happiness, says Professor Bruce Brown, a mathematician from the University of New South Wales. " Do not stop your choice on the first 37% of the girls with whom you have relationship. Statistics say that next female candidates are definitely the best."For example, the average British man has more than 12 sexual partners for a lifetime.  First 4-5 of them never become his wives. Therefore, scientists have created a formula "optimal stopping", which might determine the best time for "male action" and to maximize the chances of success.Brown formula: choose the later age when you want to marry ( H) ; choose the age at which you're ready to become a family man, if your girl is fully satisfactory to you as a future wife (P). And now all this was made in such artless formula 
H - (P x 0.368 ) 
That's right, according to the science, you can determine your optimal age for proposal lady hand and heart. Compare your feelings with numbers. This will help you to make the right decision.
