The heavy mass of fiber in bamboo stock gives this ancient species acute flexibility to exist in nature and as well in commercial use. Bamboo canes are so flexible that they can bend up to 150 - 170 degree angles without snapping in half. In the Orient, one of the safest places to be during an earthquake is in a bamboo forest. Houses made of bamboo have been reported to withstand earthquakes of 8.0 magnitude and higher. For hundreds of years bamboo has been one of the most reliable and flexible building materials known to mankind. So dear friend, if bamboo can withstand gale winds and extreme earthquakes, there should be no fear wearing your new bamboo watch to the front line of life's daily battles.
