Most of us have a ticklish spot somewhere on our bodies, and it is usually pretty easy to find. For some it’s just above the knee, for others it’s the back of the neck, and some of us go into fits of laughter if someone grabs our sides. Laughing when another person tickles you is a natural reaction. Scientists have discovered that the feeling experienced when we are tickled causes us to panic and is a natural defense to little creepy crawlers like spiders and bugs. Slight tickles from insects can send a chill through your body letting you know something is crawling on you.
That same ticklish feeling sends us into a state of panic and elicits a response of uncontrollable laughter if a person tickles us. It’s the moment that you least expect to be tickled and are that causes you to feel extremely uneasy and panicked, which leads to the most intense ticklish feeling. Even if you do know that you are about to be tickled, the fear and unease of someone touching and possibly hurting you causes you to laugh. Some people are so ticklish that they begin laughing even before they are touched. >
