TicKles!!!!!!!!!!!?

Question

Why Do you giggle when others tickle you but when you tickle yourself, you don't???

Answer 1

Tickling is basically a self-safety mechanism, in order to alert the body if contacted by foreign elements in softer parts of body.

Our body is aware beforehand that it is going to be tickled and the sensation does not happen. The nerve end of our fingers and the nerve ends of the part tickled coordinates with each other and brain does not react.

In case other person tickles, whether or not we are aware and the nerve ends sends signals of intrusion to brain and the brain alerts the whole body (that is the shake and shiver).

Answer 2

The laughter is like a panic response. When someone else tickles you, your body panics so you start laughing. When you tickle yourself, your brain and body sense no danger, so you don't laugh. I hope this makes sense.

Answer 3

Because you know where your hand is going next. It is the element of surprise and vulnerability that makes it exhilerating. There is a site on the web where you have to follow the hand on screen and move as it does and it actually works because even though it is your hand, you copy the movements and you don't know what is coming next.
Ooh, found a version on you tube for you to try, makes me laugh every time!!! =)
