Learning to protect yourself from an attacker is close to the most important quality your body can have. If you are not able to do this one thing then anyone with malicious intent can step up to you and steal or destroy anything and anyone you care about. I am not being dramatic. I am being clear.
If we stopped the narrative there, this is bad news. Depressing even.
But remember, this is a book about how to develop powerful fighting skills with a body that works partially.
