The so-called inner beauty is not a figure of speech at all, but a reality.
This fact is confirmed by a study by American scientists led by Gary Lewandowski (Gary W. Lewan-dowski), who proved that our charm primarily depends on the qualities of character *. So, honesty, responsiveness and friendliness make us attractive in the eyes of others, while boors and liars cause rejection, even if they have a model appearance. So do not get hung up on physical perfection — it is better to analyze the properties of your character.
