It’s Impossible To Tickle Yourself

When someone else tickles you, you can twitch, laugh or struggle. But try tickling yourself and you won't succeed. It is assumed that tickling appeared in the process of evolution as a means of protection from insects, spiders and other unpleasant creatures that crawl over people and can harm them. If someone else tickles you, it is also perceived as a threat. But if you tickle itself, the body will not give out a reaction, because it will understand that it is doing this to itself. But if you find it funny or unpleasant because you are tickling yourself, this is a bad sign, which can be a sign of schizophrenia or cerebellar damage.
