Here's the reason why so many couples look alike

Do you feel couples tend to look alike after one point? Turns out it's true. A study published in the PLOS One journal found that couples grow to look alike when they’ve been together for a long time.

The team examined photos of couples taken at the beginning of their relationship and then 25 years later. They found that most spouses had started to resemble one another.

Science has many theories behind this, but one of the most common explanations is 'the familiarity effect,' which is based on the fact that we tend to develop a preference for things that feel familiar to us.

Another reason behind the same is termed as 'empathetic mimicry,' which happens when people who share a strong bond develop similar facial musculature over time.

However, a 1987 study conducted by Stanford University suggested that people do not grow to look like their significant other, but choose them because of similar facial features and personality traits.
