More than 500 million people around the world are pathological nail-biters according to our medical advisers. Is it caused by nervousness, anxiousness, stress, obsessive-compulsiv e disorder, or what? There are several reasons for chewing or biting your fingernails, or even your toenails.<\/p>\n
During a summer school vacation, our medical groups invited teachers and guardians of several primary schools to present their pupils who have nail biting habit for a trip on a resort area in Nara, Japan for 40 days.<\/p>\n
Our medical groups were trying to find the cause of nail biting. However, we suspected that there is only one or two causes, primarily stress.<\/p>\n
40 pupils were gathered and the schools and guardians financed the entire expenses. After 3 hours of train trip, they arrived to a temple where they spent their vacation.<\/p>\n
No pupils were informed about nail biting. They are free to do sightseeing and going around, getting wild chestnuts, and chasing mountain dears, except at 7:00 a.m. for breakfast, 12:00 noon for lunch and 6:00 p.m. for dinner. Of course, our groups were observing their nail biting habits.<\/p>\n
