I train for the same reason I keep my shovels oiled, sword keen, my knife honed and my firearms clean and lubricated. So the tools dont rust and can be relied on to perform as best possible if they are needed.
To have self Respect. To know that I did not go down easy. That I did not always accept what is but I strive to change the conditions of the test. Everyday is a new test for us: TO BE OR NOT TO BE. To have actually lived a life worth living before we die.
