Good to see our boys and girls in the services having fun in this tickling video. Tickling is actually a reflex from our prehistoric selves in which small ants would protect us from infection and cause us to smile. Titillation maneuvers have long been used in the military to train against interrogation. POW's are tickled into revealing classified information, and in this war on terror we can’t afford to lose even the smallest battle.. This training exercise is captured in this intense tickling video.
