Our reaction to be tickled may be nature’s way of encouraging self defence training from an early age.

BrainCraft was created by Vanessa Hill (@nessyhill) and is brought to you by PBS Digital Studios. Talking psychology, neuroscience & why we act the way we do.

A big thank you to Anna from Gross Science, Kelsey from Infinite Series and Jacklyn from SciJoy for being tickled for this episode.

And thanks to Deep Look for their epic mosquito shot: https://youtu.be/rD8SmacBUcU
