I have been practicing martial arts for a long time. I do it for the flexibility, strength, reflexes, mental, emotional and physical challenge... it also gives me the confidence to face situations, knowing that I have skills to defend myself, my partner and my patients.
I did not get into this business to hurt people. I find that 99% of the time, the ability to assess a situation and people and quiet, respectful confidence disarm most violent confrontations. If the situation becomes violent, then I have screwed up. I missed or misinterpreted something.
If the situation becomes violent, my first recourse is escape - for me and anyone else in harms way. I don't have to prove anything to anyone. I firmly believe that I cannot hurt another person without hurting myself. Physical self defense is the very last resort.
I am very uncomfortable with macho men taking an 8 hour course and then going out loaded for bear. Decades of martial arts training makes me more and more peaceful and non-violent. Only an idiot would think that 8 hours of self defense training equips you to do clipboard therapy.
