Tickling is a strange phenomenon often experienced as a kind of itch (aka Lady Stefanie / Cruel Reell) triggered by a more or less light touch on certain parts of the body. The effects of tickling can range from a pleasant tingling sensation to an uncontrollable fit of laughter, as well as produce very interesting acoustic transformations. Some scientists believe that tickling is a kind of protective mechanism that warns us of harmful insects or annoying dommes. (GERMAN CLIP)
