If clinical psychologist Linda Blair is to be believed, finding your perfect partner could be just one easy step away.
In her new book 'Birth Order: What Your Position In The Family Really Tells You About Your Character,' Blair claims that the factor that exerts the most powerful influence on us all is the order in which we're born. It doesn't just affect our character, but also career and relationships.
A person who was the first child born has different traits than those born in the middle or the last, reports the Daily Mail.
So, for example, if he's a last-born and you're a first-born, you'll probably find that you get on extremely well. But if you're both only children, there could be problems ahead.
For instance: first-born and a last-born: The maxim that 'opposites attract' makes a good starting-point, because first-borns often make a good match with a last-born, sometimes a perfect match, says Blair.
Simply because the eldest in a family is likely to be an organised and caring person while a last-born enjoys being dependent on someone else, but also tends to be less organised.
Not only that, but the youngest in a family is usually more fun-loving than the eldest, who can do with having a bit more lightness in his/her life.
However, there's one issue - last borns are passionate about their beliefs, a quality that might clash with the type of conventional first-born who insists on setting all the house rules.
