[00:00:00]Tickle yourself right now. It does not work. Team dangerously ticklish. This is for you. Try it. In 1998, neuroscientists at University College London put people in fMRI scanners and tickled them. A robot tickling a stranger triggered full laughter.

[00:00:20]>> This is so funny.

[00:00:21]>> The same robot controlled by the person being tickled. Silence. The brain knew it was coming. The moment you reach for your foot, your cerebellum fires a prediction signal 100 milliseconds ahead of your hand. It tells your touch cortex. This is you ignore it. Your brain cancels the signal before you feel it. When someone else touches you, no prediction exists. The signal hits raw.

[00:00:52]That is why you scream when a friend grabs your foot. Right now, your brain is cancelling sensations 1/10enth of a second before you feel them. Every blink, every keystroke, you have never felt yourself the way someone else does.

[00:01:10]Send this to the friend who screams loudest when grabbed. Comment tried it if you just did. The next one is about something your eyes do that should be impossible.
