I have heard of "husband and wife look alike", but what the hell is "human-dog look alike"? !

According to a study by Weird Psychology author Wiseman: People who keep different pets have different personalities. People who keep fish are the happiest; people who keep dogs are the most interesting; people who keep cats are the most reliable and emotionally sensitive; and people who keep reptiles are the most independent. It is currently believed that this may be because some people subconsciously regard their pets as another version of themselves. Therefore, they adopt pets with similar "personality traits".

Compared with "pet look-alikes", "couple look-alikes" may be more famous. Both experience and science have proven that couple look-alikes exist. As for the reasons for couple look-alikes, there are currently two mainstream views, and both have been proven: First, in the process of choosing a mate, humans tend to look for a partner who looks similar to them as a marriage partner. Second, couples will influence and imitate each other in the long-term process of getting along, and with the convergence of eating habits, they will eventually look like couples. However, having couple look-alikes does not mean that the marriage will be happier. There is currently not enough evidence to prove this.
