What does it mean to say that a person's brain is abnormal?

No way ~ ~ ~ People say that the brain is not normal, which is just an oral expression. Very casual expression. If you write it, it should be a psychopath ~ ~

Now many people are in sub-health state, which is normal. What we need is adjustment and adaptation. If a person has never experienced anything and all his thoughts are normal, then such a person does not exist. Many ideas come from natural laws, but now many natural laws are still being discovered, so there will be too many misunderstandings ~ ~ ~

Just like obsessive-compulsive disorder, people who don't know may think that their brains are abnormal, but people who have knowledge will think that this is just a small cold! !
