Identical twins are very similar. Are there two identical people in the world?

First of all, I have to admit that many identical twins are very similar when they are young or when they grow up, especially wearing the same clothes and keeping the same hairstyle. It's really hard to tell people who are not very familiar with them, and even the idea of mistaken twin wives or husbands in many jokes comes from this. But there are really no two identical people in the world, even identical twins, because they are more or less different in details in physical appearance. After a long time with them, they will find that their personalities, temperament and eyes are also different.

When we first see a pair of twins, we will find that they are strikingly similar in appearance, even including their height, figure and expressions when they are sad or happy. However, with the increase of familiarity, we will gradually find the subtle differences in their figure and appearance. For example, the twin sister's face is relatively clean, and there are a few small spots on her face. Her face is slightly wider and her chin is slightly pointed.

Temperament and eyes are different. When I first came into contact with twins, many people really couldn't tell them apart. They often regard their elder brother as their younger brother, or their younger brother as their elder brother. That's because when they first came into contact, human observation was limited and they could not be distinguished well. Long-term contact can not only find small differences in appearance and body shape of twins, but also find differences in temperament and eyes of twins. Many times, we can tell who is the elder brother and who is the younger brother according to temperament and eyes.

The real experience is that I once worked in a factory. Coincidentally, there are four or five pairs of twin workers in the factory. At first, it was difficult to tell them apart. I thought they looked the same. But after working for a period of time, I found that they are not difficult to distinguish, and it is easy to find differences in body shape and appearance, even in height and thinness. No twins are very similar in appearance. So there are really no two identical people. Many photos of twins on the Internet were taken by photographers after dressing them up, so they look almost identical.
