There are things like normal and there are things like abnormal. How do we know what is normal or abnormal? Sometimes, as time passes, we realize the previously abnormal looks normal, and vice versa. There are blurring lines between them. When it comes to nature, all things are natural and look normal. Likewise, it should be cautious to apply the concept of normal vs. abnormal to humans. Can we say "I am normal" anytime and under any circumstances? If so, what is the basis for it?
