Tickling is a simple way of having temporal fun between humans; normally between kids, teenagers and young adults. It generates "contagious" laughs and smiles that are evaluated as beneficial for the human body when it is done properly. The unhealthy body of old people can't handle tickling very well. Aging sucks.
