“A sharp mind is the warrior’s edge.”
You can learn more by reading ‘Sharpening the Warrior’s Edge’ which is the first text which examines survival and combat performance from a scientific perspective.
Author Bruce K. Siddle methodically brings together one hundred years of research which identifies the relationship between survival stress, the heart rate and combat performance.
Most importantly, Siddle explores the psychological and spiritual components which establish the warrior mindset.
This pioneering test is a must read for present-day warriors, or anyone involved in use of force, combat or martial arts training.
