Tickling is an act of evoking involuntary laughter by touching a part of the body. Some parts of the body are more ticklish than the others, the reason for which is still unknown. When used in sexual fetishism, the act of tickling is called as "tickle torture". Research by Dr Sarah-Jayne Blakemore of the Institute of Cognitive Neuroscience in London found that robotic arms used to tickle people are just as effective as human arms. Men and women are just as "ticklish". But a few studies suggest that, men may be slightly more ticklish than women. Research headed by Dr M Blagrove from the University of Wales in Swansea shows that the normal tickling response may be absent in those with schizophrenia. Tickling was used as a torture by the ancient Romans. The most surprising feature that can be experimented personally is that if one tickles oneself, there is no such stimulation or laughter.

Kitchen forks have been endlessly evolving for the past millennium or so. But a historical background check will put its origins somewhere in Greek. Initially used for the carving of meat, the fork comes to the dining table pretty late. It was around the 7th century that royal courts in the Middle Eastern Muslim world started to use the fork on the dining table. In another century, they were passed on to the Byzantine world, where the use of forks at the dining table became symbolic in wealthy and noble families. The fork was later carried on to Italy through a matrimonial alliance with the Byzantine. After a long dormant period, the flow continued into Francem when Catherine de Medicis married Henry II. The Fork came to the English notice by a man called Thomas Coryate, who brought forks to England in 1608. It took a very long time for the English to take up the fork as it initially met cultural resistance.

The dispute between India and Pakistan regarding the territory of state of Jammu and Kashmir is the oldest and longest surviving dispute on earth. India claims that Kashmir is an integral part of India. Pakistan claims that people of Kashmir are the ones that should determine their own future. Both countries refuse that region should be independent. The dispute has consumed millions of lives on both sides apart from trillions of dollars since 1947. The Kashmir dispute is now registered in the Guinness Book of World Records as the largest militarized territorial dispute currently on the planet.

One of the major points that Facebook scored over all of the other social networking sites, at least initially, was its stringent privacy settings that gave you a sense of security and safety regarding the contents of your profile on Facebook. However, with the advent of Twitter and other such sites, Facebook might be in a mood to keep up with the growth of its competitors - and this might be why now Facebook content is easily accessible to strangers and gone are the days when you had a sense of privacy that only you and your exclusive friends shared on the network.

A female eagle is ten to twenty percent larger than a male eagle. In Zoological terms, heaviest means largest, according to which, the Philippines Eagle would be the largest, but actually speaking, the Harpy Eagle scores better. If the longest wing span is considered, the longest span is of the Wedged tailed Australian eagle, with an estimated wing span of 230-250 centimeters. The largest ever is the Haast's Eagle, also called Harpagornis Moorei. It is 4.5 feet long with 10 feet across the wings and weigh at least thirty three pounds. This species of eagles is now extinct. The Steller's sea eagle is the heaviest living eagle weighing fifteen to twenty pounds. The Philippine eagle, also known as monkey- eating eagle has the largest physical dimensions with Harpy eagle being the bulkiest.

Diaphragm is a dome shaped structure which has several large muscles which naturally separates any two adjacent parts in a human body or body of the mammals. The thoraco abdominal diaphragm is the commonly known muscle. Considering a human body, these muscles serve to part the cavity of the chest from that of the abdomen. The diaphragm top is located one and one and a half inches from the bottom of the sternum supports the heart, and diaphragm bottom is attached round the lower ribs connecting to the lower lumbar vertebrae. Being the chief part of the respiration process in humans, these muscles rest into dome shape during exhalation. It contracts when air is inhaled; it lets the chest cavity expand by a simultaneous contraction of the chest muscles. When air is deeply inhaled followed by the expansion of the belly while inhalation and retraction, while exhalation, the diaphragm moves further down into the abdomen, thereby making the lungs expand completely in the chest cavity. This suggests that more amount of oxygen is inhaled and carbon dioxide is exhaled. A quick breathing may cause hyperventilation due to the loss of required amount of carbon dioxide.

The First President to be born in a hospital, a student of Nuclear physics and a speed reader who can read almost 2000 words a minute, Jimmy Carter once panned for Gold too.

In a bizarre version of one of the most thrilling (and tough) games - namely ice hockey - the two teams of six members each fight against each other to score a goal under 6 to 8 feet of water. The players wear fins for speed and agility, and also use masks and snorkels for air - however, for the most part; the heavy lead puck has to be maneuvered with a sort stick of about a foot long while holding your breath underwater. There are elaborate rules for this game and nationwide championships are also held regularly. You can even become a member various Underwater Hockey clubs spread all over.
