Book Comments/Reviews:

     "Just got a copy of your Karate-Lifespans book. Outstanding! This is the kind of thing that we need in karate." 
                                                                                                                         Hanshi John Sells, 8th Dan
      "I recommend to ANY who haven't read it, to please do so. It is not only thorough, but enlightening no matter
       how long you've been in and around martial arts, and no matter what your rank. In fact, the longer you're
       involved and the higher your rank, the information in this book just may apply to you....more. Kevin Harness
 
       "To all my karate friends, I whole heartedly recommend this publication. A remarkable product of meticulous research,
        laced with provocative facts make this a must for any serious karateka. Renshi Jason Griffiths, 5th Dan

Content assembled by & related to:

  - multiple doctors spaning medical reserach, clinincians a psychologist & karate practitioners
  - the data shows that lifelong karate practice in different styles has different effects on lifespan
        - regional effects (East, West, post WWII until today & comparisons to karate-ka born in the 1800s)
        - differing types of inflammation and how it possibly ties to karate longevity
        - sparring, drills, ude tanren and kata like sanchin how do each of them really impact longevity
        - dojo cultural considerations
        - the effect of the developed karate persona & combative environments on longevity

Polls show that people have the misconception that karate lengthens one’s life, when in fact the data shows the opposite (via analysis of over one hundred 8th dans in the East & West). If we notice a truth in the data in art that seeks enlightenment, be it good or bad, it should be discussed & hopefully the results will lead to better outcomes for elite karate-ka in the decades to come.

We examine the central topic of longevity & karate by using instructor lifespan data, a review of medical diagnostics & research, longevity research encompassing sports physiology, karate psychology and behaviour patterns which has shown to be tied to longevity (over 270 references reviewed & cited). We also discuss some interesting statements on the topic by passed masters such as Itosu of the 1800s, Shito-ryu’s Mabuni, Asai of Shotokan who openly stated health may not go hand-in-hand with budo. Despite the fact that karate provides many upsides for its practitioners, why does it appear to reduce lifespan & what can be done about it? 

In generating the data for the book, we factored in the decade and year sensei(s)  died in, their geography and given those variables, at what age they should have died at using what are called life expectancy at birth statistics and life expectancy by age statistics. Although the books focuses on sensei’s ages of death in recent decades, we also compare to famous karate sensei who were born in the 1800s. Furthermore, we compare the data to other Western sports, Olympians and martial arts like judo. All of these groups allow us to flush out hypotheses around the variables that may be affecting lifespan and talk about diagnostics or possible training or behaviour change. 

Doctors practice a system called “Evidence based practice” abbreviated to EBP, this is a process of analyzing data to decide on a scenario and ultimately prevention or treatment. We as martial artists should also train with an evidence based practice approach given recent decades has resulted in the collection of extensive data for street fighting statistics, sports and health. 

Of course even outside of the martial arts, the image of wise karate masters reaching an old age appears to be well burned into the mind of most people in society and the data can be confronting because ‘everyone knows of an instructor that lived to a very old age’ and may cause many to argue that karate is in fact healthy in terms of enabling a long life. While by no means of the same severity, such a lack of evidence-based thinking is similar to the arguments some smokers give, “I know this guy who has been smoking all his life and is now 85”. Of course such people exist but they are the exception to the probable outcome. Funakoshi sensei, the founder of shotokan, is a great example of an exception to what the pooled karate longevity data indicates. He lived an amazing life spanning the samurai era in Japan, through two world wars and into the era of jet planes and space rockets (Funakoshi, 1956). But his longevity is an outlier amongst karate-ka. In fact, when one looks at some of his practices, such as banning sparring (an inflammation creating activity), no alcohol consumption, rarely eating meat etc., there may be arguments as to why his karate did not negatively affect his longevity - and we explore these links in this text.

This book is the 2nd to be published in a series of 3 books to put data (evidenced-based knowledge) into the practices of karate. The trilogy is aimed at gathering clinical and university researched data for the 3 pillars of karate, known as shingitai in Japanese. In Western lingo it is called ‘mind, body & spirit’ (direct translation: mind - shin/kokoro, technique gi/waza and body - tai/karada). In this context of shingitai, ‘body’ may encompass both technique and health.
