WEST BENGAL GOJU-RYU KARATE-DO ASSOCIATION

DURING KUMITE :
A young man uses 90% physical strength and only 10% mental strength. When it comes to a middle-aged man, that ratio is 50:50. A person over 65 or 70 years old uses 10% physical and 90% mental strength. No matter how bad it may seem, the sum of the two is still 100%.
