18 scientific curiosities encountered in everyday life

After a bath, you're greeted by long, tangled strands of grime that roll out like noodles! Did you think you had to scrub them cleanly? While we often think of grime as dirty, it actually plays a role in protecting our skin's health.
In Volume 3 of "The Common Curiosities of the Common Siblings," the question is, "Why do we have such petty times?"
Here are 18 curiosities that you might have wondered about at least once in your daily life, such as, "Why does sweat smell musty?", "Does a big head mean higher intelligence?", and "Does watching scary movies make you feel refreshed?"

Scientific knowledge in your head!

In the 'Warm-up Quiz' corner inserted once every six episodes, you can learn the key concepts learned in the text by solving simple quizzes such as the initial consonant quiz, the four-headed question quiz, and the crossword quiz. In the 'Curiosity Level Up' corner inserted at the end of the book, you can review the content learned in the text as a whole by solving fun four-option multiple-choice questions.
As you read the comics and solve the problems, the scientific information in the text will become ingrained in your head without you having to memorize it.
