Example: During WWII, my granddad was a scout in the Austrian Alps and had to climb 5 kilometers, up hill, every day. He perfected the army shoes for three years and after the war he founded our company. / We were always skinny when we were young and everybody made fun of us. Then my brother started to learn Kung Fu from a Singapore master and we became suddenly well respected and popular. A year later my little sister was mugged and ended up in wheel chair for two month because she couldn't defend herself. I felt horrible not being able to protect her, so I decided we were going to teach her and others self-defense, so such things wouldn't happen again.
