...If yes, then you will realize Ki are for Wussies.... Yoshinkan' ers believe in Body Mechanics, Angles, you know.... the boring Physical stuff....
What happens if you're sick, injured or just plain old and can't rely on your strength alone to overcome an opponent? Is dying your back-up plan?
It's not about the dog in the fight. It's about the fight in the dog. Therefore this is really about Mind

The Yoshinkan I've seen is about timing, balance, ki extension and doing movements in a correct manner. Maybe that's just my perspective.
