안녕하세요! Cristi입니다.
저는 관절 꺾는 소리가 잘 안나요ㅠㅠ
나봤자 완전 조그맣게?
관절 꺾는 것을 보면 멋있어 보이더라고요.
저는 관절 꺾는 소리가 안 나는 종류의 관절을 가지고 있나봐요~
Many people crack knuckles. They crack it to look like that they are clever, or some people do it because it feels good. There are lot of reasons why people crack knuckles. Some people say that cracking knuckles are not good for our health, and some people hate the sound which is made when people crack knuckles. Recently, scientists have studied about knuckle cracking and the relationship to the human joint. And the result was that knuckle cracking causes tremendous damage to the human joint.
