Query: excellent book for self defense

This is a great book on self defense (not a martial art)... it will work for one who doesn't want to spend years trying to perfect their "Dim Mak" death touch. You can use this book with a partner and by oneself (I would recommend a heavy bag at least and if you have the money a "Bob" body opponent bag). This book has a lot in common with Fairbarn, Styles type of combatives (which is the newest old thing in self defense) also has elements from what Kelly Mccann teaches in his combatives book / videos (which I recommend also if you want a more rounded education). Tegner does teach fist blows (which is a drawback) but all the other blows are standard combative fare.
