Question

When you are tickled why do you laugh even though you don't like it?

Answer 1

It's believed to be a nervous reaction to the stimulus.

Answer 2

Definitely an automatic response of the body

to tickling. Sometimes I get tickle-tortured

until I am crying, but I'm still laughing

hysterically even though I am suffering

horribly from the tickling. That makes the

tickle-maniacs who are torturing you think

you're having a great time, because you

are laughing. The forced laughter is healthy

but when they tickle us for hours its

way out of hand. You would think they'd

get the message when we are peeing

and our eyes and nose are running all over!
