The outermost part of our skin, known as epidermis, is bundled with several nerve endings. These nerve endings are responsible for analyzing the touch and thereafter informing us whether it was pleasurable or not. The parts of our body which have the least bones are the most sensitive parts like the stomach or our feet bottom. Scientists believe that tickling puts our brain into ‘flight or fight’ mode. The squirming we do, when we are tickled, is a form of our defence mechanism. We compress our body where it is being tickled and reduce the area available for more tickling.
Why are we ticklish in only some places?
