Now tickling, yeah that is fun and could make someone burst into laughter. But did you know that tickling is an act of torture. During the old times and also during the world war 2, tickling was made used to torture people and inmates and that could eventually lead them to death. First of all they victim would burst into loud laughter and then eventually he will cry and suffer from pain if the tickling wasn't stopped. Because on the feet and armpits and other parts there are many nerve endings and these nerve ending are very sensitive.
