After 30 seconds slowly lower your body forward and to the outside of your left leg, keeping your left arm fairly straight as you do. When you reach your lap remain there for another 10 seconds, release the pressure but rest there for another 30 seconds. Then reverse your hand positions and do your right side.
Inhaling a high concentration of natural gas can lead to asphyxia, the symptoms of which include fatigue and chest pain. Asphyxia occurs when your body is deprived of oxygen, and the more carbon monoxide there is present in the air, the less oxygen you'll be able to inhale, which can potentially kill you.
The use of natural gas is also rapidly increasing in electric power generation and cooling. Natural gas is the cleanest burning fossil fuel, producing primarily carbon dioxide, water vapor and small amounts of nitrogen oxides. The prevailing scientific theory is that natural gas was formed millions of years ago when plants and tiny sea animals were buried by sand and rock.
