Moreover studies have proved that physically active children achieve more in class. The national association for sports and physical education recommend at least sixty minutes of exercise daily or for most days of the week. Statistics show that over ten million children aged between six and nineteen are over weight in the United States. Among the adolescents, the number of the over weights toady is four times than in the last decade; a very alarming rate. The dangers of being overweight are too adverse to be true. Some of the health risks associated with obesity and overweight are polygenic disorders like pre-diabetes and diabetes, heart diseases, hypertension, hyperlipidemia, apnea and many more. Additionally, nutritionists say that an obese child is likely to be an obese adult. The fact that fat cells are capable of increasing in number during childhood but in adulthood the body system can only work to fill the existing ones and not to form new ones supports this claim. Obesity is a major health concern in most of the countries and especially in the US as aforementioned. Obesity is hard to manage not mentioning its health related risks; it calls for specialist medical care, which is very expensive to a given country; therefore, nations cannot afford to cut down the programs that hel p to manage and/or prevent obesity.

Physical exercise in schools should draw their support from family members, the society and the government. The government should set aside money for physical exercises in particular in the national budget as it does not only affect the students positively but also saves the country’s economy greatly for a ‘sick’ nation is an unproductive nation. There are other benefits associated with physical education, which should compel parents and the government to embrace the activity. Physical activity improves on the students overall confidence; for instance, performing in the field instills courage in the student. In addition, many students learn of their talent s in school sports most of whom secure sporting jobs internationally which is beneficial to the individual student, the parents and the nation and this underscores the need to revive this dying yet necessary activity. Physical activity also promotes a healthy lifestyle in adulthood. Students grow into responsible citizens who influence their children positively; the best news is that this behavior passes from generation to generation hence giving rise to a healthy nation. Hygiene and sex education are part of the physical education curriculum. These work together to give birth to an all round person. Another virtue learnt is teamwork as most sports in schools are holistic and this promotes the spirit of unity in a student’s life. The factors above would be lost if the government does not intervene to save the dying physical education. Schools will not be a place of molding one into a responsible citizen, as the curriculum would be incomplete without physical education.Advert ising We will write a custom essay sample on Physical Education and Its Benefits specifically for you for only $16.05 $11/page Learn More This essay on Physical Education and Its Benefits was written and submitted by user Kallie F. to help you with your own studies.

The 4,000 Year Old History of Locks

The 4,000 Year Old History of Locks Archeologists found the oldest known lock in the Khorsabad palace ruins near Nineveh. The lock was estimated to be 4,000 years old. It was a forerunner to a pin tumbler type of lock, and a common Egyptian lock for the time. This lock worked using a large wooden bolt to secure a door, which had a slot with several holes in its upper surface. The holes were filled with wooden pegs that prevented the bolt from being opened. The  warded lock  was also present from early times and remains the most recognizable lock and key design in the Western world. The first all-metal locks appeared between the years 870 and 900, and are attributed to the English. Affluent Romans often kept their valuables in secure boxes within their households and wore the keys as rings on their fingers.   During the period of the 18th and 19th centuries - in part to the onset of the Industrial Revolution - many technical developments were made in the locking mechanisms that added to the security of common locking devices. It was during this period that America changed from importing door hardware to manufacturing and even exporting some. The earliest patent for a double-acting pin tumbler  lock  was granted to American physician Abraham O. Stansbury in England in 1805, but the modern version, still in use today, was invented by American Linus Yale, Sr. in 1848. But, other famous locksmiths patented their lock designed before and after Linus. Robert Barron   The first serious attempt to improve the security of the lock was made in 1778 in England. Robert Barron  patented a double-acting tumbler lock. Joseph Bramah   Joseph Bramah patented the safety lock in 1784. Bramahs lock was considered unpickable. The inventor went on to create a Hydrostatic Machine, a beer-pump, the four-cock, a quill-sharpener, a working planer, and more. James Sargent   In 1857, James Sargent invented the worlds first successful key-changeable combination lock. His lock became popular with safe manufacturers and the United States Treasury Department. In 1873, Sargent patented a time lock mechanism that became the prototype of those being used in contemporary bank vaults. Samuel Segal   Mr. Samuel Segal (former New York City policeman) invented the first jimmy proof locks in 1916. Segal holds over twenty-five patents. Harry Soref   Soref founded the Master Lock Company in 1921 and patented an improved padlock. In April 1924, he received a patent (U.S #1,490,987) for his new lock casing. Soref made a padlock that was both strong and cheap using a case constructed out of layers of metal, like the doors of a bank vault. He designed his padlock using laminated steel. Linus Yale Sr.   Linus Yale invented a pin-tumbler lock in 1848. His son improved upon his lock using a smaller, flat key with serrated edges that is the basis of ​the  modern pin-tumbler locks. Linus Yale Jr. (1821-1868)   American, Linus Yale Jr. was a mechanical engineer and lock manufacturer who patented a cylinder pin-tumbler lock in 1861. Yale invented the modern combination lock in 1862.
