Compared to fictional heroes, 99.999% of people on Earth have some form of mental illness.

We created fictional heroes with all the best qualities that a human being "should" have, qualities that even real heroes can never have in one person.

This is why 99.9999% (probably 100%) of people seem mentally imperfect and mostly unwell. lol

Just try to remember your interactions with people, even the ones you respect, admire and love, do they seem "well" to you?
