在这个充满神秘与迷信的世界中，许多人都对一些古老的信仰情有独钟。从敲木头到数字13，这些看似无厘头的习惯，背后却隐藏着奇特的历史和文化渊源。尽管这些迷信缺乏科学依据，但它们为何能在现代社会中生存下来？让我们一同探索它们的起源与意义。
Are you afraid of black cats?
Would you open an umbrella indoors?
And how do you feel about the number 13?
Whether or not you believe in them, you're probably familiar with a few of these superstitions.
So how did it happen that people all over the world knock on wood or avoid stepping on sidewalk cracks?
Well, although they have no basis in science, many of these weirdly specific beliefs and practices do have equally weird and specific origins.
Because they involve supernatural causes, it's no surprise that many superstitions are based in religion.
For example, the number 13 was associated with the biblical Last Supper, where Jesus Christ dined with his 12 disciples just before being arrested and crucified.
The resulting idea that having 13 people at a table was bad luck eventually expanded into 13 being an unlucky number in general.
Now, this fear of the number 13, called triskaidekaphobia , is so common that many buildings around the world skip the 13th floor, with the numbers going straight from 12 to 14.
