2. Also think about ergonomics; a desk should be around 29 to 30 inches high and 3 1/2 feet from the desk to the chair.
3. Choose the correct office chair. A chair needs to be adjustable to allow for the height of the person, provide adequate support for the lower back and comfortable seat padding. The armrests should be adjustable and arms and shoulders should be relaxed at the correct position.
4. Ensure you have adequate lighting. Too much bright light in your field of vision can cause visual discomfort, and reflections on your computer screen can make it difficult to see what is displayed. If possible position your desk at right angles to the window for the best use of light and to minimise reflections. Use a free standing desk lamp for extra lighting on paperwork.
5. Finally consider the temperature and humidity in the room. A comfortable temperature for sedentary work is between 20 and 24 degrees C. If the room is too warm or cold and draughty then this will cause discomfort. Place a water loving pot plant in your office to help keep the humidity to a comfortable level.
The strength of the ship building materials were vital because approximately 600 years ago the Chinese commissioned by the Ming dynasty to sail to the edge of the world. Year later the British naval ships were made from Oak whish is also a very hard and durable wood. The British encountered two problems with oak: Wood Worms and a shortage of Oak trees. Woodworms were destroying the ships in the British Naval Fleet and were the scourge of wooden ships throughout history. It could take 850 oak logs to repair one ship. It took a little over 2000 oak logs just to build one ship. The British needed ships as they continued for some time to have maritime issues with the French and to be able to go on to conquer and take control of British colonies. The British naval fleet was their primary means to accomplish this.
The British knew about the Teak wood used on the Chinese ships and how strong and rugged they were after having run into them, literally in the shipping lanes. The British had learned how impervious these ships were to all of the elements at sea: Saltwater, ocean wind, and the blistering sun. It was also found that Teak was difficult to splinter when hit by gunfire or artillery fire. This was a very important issue as splintering wood was the major cause of casualties among naval warfare in the eighteenth century.
Britain was very interested to grow and produce this wood. The British quickly realized they did not need to grow Teak Wood as they could occupy those countries where the Teak wood was grown and have a plentiful supply. India, Thailand and Burma were quickly annexed into the British Empire. This of course is not the main reason why the British took over these areas, but it certainly helped to give reason. Myanmar (formerly Burma), which is just south of India, and Yangoon became the first places where Teak was being cultivated for British ships. Calcutta was set up as another British shipbuilding site. All of the British merchant ships built in Calcutta were built with Myanmar Teak logs which were said to be the best. Once the wood was depleted from India, logs were harvested from Thailand and Burma.
Teak forests were quickly being depleted and forests dwindling. Teak was now the preferred wood used for building ships, Yachts, Ocean liners and furniture. Under ocean conditions, the wood had minimal warping, cracking or shrinkage. This meant little maintenance. The wood was also impervious to wood rot and insects, like the mighty woodworm. The famous Ocean liner “Queen Mary” used no less than 1000 tons of teak when built. The British understood the depletion that was taking place and developed a re-forestation plan. They appointed a leader to head a new department and began replanting Teak trees on what are now called
Teak “plantations”. A set of very strict laws were enacted regarding who can cut Teak Wood and who can purchase it. Once these laws were set in place, one needed to have permission from the British Government to be able to cut a Teak Tree down and or export it.
Teak was also being used by the locals for huts, fence posts, and furniture. Today India is the third largest importer of Teak , followed by China and Japan. As much as 80% of India’s timber consumption is Teak. The wood is used in India today for local consumption; building homes, furniture, fencing, etc. It is the one wood that can withstand the monsoons, the scorching heat and the humidity.
Teak Wood contains natural oils and Silica (sand) which makes it impervious to insects, and wood rot. These natural substances also help it to maintain its appearance for many years.
When many of the English ships of WWII were taken apart for salvage, the Teak Wood decks were re-manufactured into outdoor furniture such as park benches. Even today they can be seen in many parts of Europe still preserved and functioning.
