This is not a book of science. Nor is this a Taekwondo manual. For, you won’t be able to learn science, nor secrets of Taekwondo through the book. This book is all about ‘Taekwondo,’ and ‘science,’ only to the extent anyone who has ever exercised Taekwondo would already know. Ironically, however, this book will function as a book of science, and as a Taekwondo manual. For, those who know Taekwondo would get to know more about science, and vice versa.
