Martial arts gave me my identity, my purpose, a passion for a pursuit in life. I wasn't particularly good at sports, I didn't have many friends, and was a bit of a loner. Martial arts changed everything. I finally found something I was good at... it became my identity... it helped my confidence... it gave me a social circle!

Disasters keep coming along at random intervals, they are not normally distributed. They either come randomly (in the case of war) or they are governed by power-laws (pandemics and earthquakes).
