Ever tried tickling yourself? Wondering why it didn't work? When I was a kid, everybody was like that😉 The thing is that we need this peculiarity of perception (the sense of tickling) to recognize the threat. This is how we recognize various threats - insects, for example. You can hardly expect good things from them🙌🏻 We have little chance of seeing or hearing insects, so tactile sensations come in handy. But when we tickle ourselves, the body is well aware that this is not a threat☝🏻
