Some of us fidget when we're confronted with an uncomfortable situation. A person who fidgets by tapping a foot nervously, jiggling a knee up and down or crossing his legs and swinging the top one back and forth repeatedly in Japanese is known as being involved in "bimbo-yusuri" which literally "poor shaking."

There are a million explanations that have been implied for this type of unconscious action. Some call it nervousness, grouchiness or feelings of agitation. However, there are people who find it really annoying to see others fidget. If you are unable to stop yourself of doing it, Nikkan Gendai has very useful news for you.

A recent British study shows that mortality risks among females between the ages of 37 to 78  are groups who sat for over 7 hours or more at a time, and those who do not engage in leg-swinging have a 30% higher risk than those who sat for five hours or less. However there was no noticeable increase that was observed in either group who habitually fidget. The researchers, who published the results of the study in a U.S. online medical journal, guessed that the foot tapping and leg jiggling may lessen  the fatality risk among those who sit for prolonged periods.

Sedentary behavior, prolonged sitting included, is considered as a causal factor in a various sickness, including diabetes and cardiovascular disease.

Dr Koki Shin, director of the Shin Clinic in Tokyo's Ota Ward, explained that the brain stops transmission of electrical pulses to the leg muscles while on a sitting position, and metabolism lowers.  Over a period of time, this lifestyle may lead to obesity and not moving the legs may add to the risk of acquiring type-2 diabetes. According to a study, prolonged sitting may heighten the chances of acquiring diabetes by 91%.
