Many people have problems that they are only aware of through symptoms like head aches or back pain that result from imbalances in muscle tightness. This book explores stretching, systematically.

The book is divided into four parts. The first, entitled “Stretching Fundamentals,” presents fundamental principles and background information. Besides basic guidelines for stretching, it also discusses anatomy and physiology of the muscular system at a rudimentary level.

The second part is about targeted stretches, and it forms the heart of the book. This section, literally, goes from head to toe (and then back to the arms) explaining techniques for stretching major skeletal muscles. For some muscles, there is more than one stretch shown, but for others there is just one. Each entry on a muscle is divided into two parts. The first, “Muscle Facts,” describes the muscle, the causes of tightness, the symptoms of tightness, tests to gauge how tight the muscle is, and any precautions that should be considered when stretching the muscle. The second presents the stretching technique with a line drawing and mention of any mistakes to avoid. There are a mix of solo and partner stretches, as well as those using a ball.

The third part presents programs for pain relief. There’s a useful section that discusses morning aches and pains, and the ways in which one is sleeping might be leading to a crick in the neck or shoulder pain. This section not only lists the muscles that one should stretch to address various issues, but it gives little anatomical drawings in the context of the stretch that both help show what one is stretching and gives a reminder of the stretch.

I came to this book from the perspective of a yoga practitioner and teacher. If you’re wondering how these stretches differ from yoga, a major factor is that balance is taken out of the equation. The stretches in the book are done in a stable position. The downside of this is two-fold. First, if you want to build and maintain balance, you need to do an entirely separate set of exercises for that (depending upon the condition of the individual that could be necessary or a waste of time.) Second, one needs access to a wide range of equipment such as tables, adjustable benches, etc. (not to mention a partner, in some cases) to make these exercises work. The upside is that the individual is in a safe and stable position, so if they have poor balance they are at minimal risk.

The last section is one assessing flexibility and muscle balance. People think more about the former than the latter, but for most people, how balanced opposing muscle groups are probably contributes more to painful problems in the body. Because some muscles are easier to stretch than others, a book that shows how to get to the more challenging muscles is a great thing to have.

The ancillary matter includes a variety of graphics (mostly line drawings and anatomical drawings), a section upfront on the major components of the muscular and skeletal systems, and a references section in back.

I found this book to be useful and informative. I’d recommend it for individuals such as trainers, yoga teachers, athletes, and others who want to understand stretching at a level beyond technique.

BOOK REVIEW: Sound Medicine by Kulreet Chaudhary

Sound Medicine: How to Harness the Power of Sound to Heal the Mind and BodySound Medicine: How to Harness the Power of Sound to Heal the Mind and Body by Kulreet Chaudhary
My rating: 4 of 5 stars

Amazon page


The Longfellow poem “There Was a Little Girl” has a line that says, “…When she was good, She was very good indeed, But when she was bad she was horrid.” That’s kind of how I felt about this book. At its best, it reports findings about how practices involving sound (i.e. mantra chanting) effect health and well-being, and lends insight into why sound sooths. At its worst, it tries to sledgehammer the square peg religious / spiritual practices into the round hole of quantum physics and foundational physics, often engaging in leaps that are at best wildly speculative, while presenting them as though they are as likely as not.

My favorite professor from undergraduate studies was a folksy Religious Studies Professor who cautioned against two opposing fallacies. The first he called “the outhouse fallacy.” This is assuming that because people of the past didn’t have indoor plumbing that they were complete idiots. Let me first say that, until recently, yoga (and other complementary health practices) suffered its fair share from this fallacy among doctors and the scientific community who felt that it couldn’t possibly help with health and well-being because it wasn’t rooted in the latest scientific findings. However, there is an opposing fallacy that my teacher called the “firstest-is-bestest” fallacy, which assumes the ancients figured it all out and we are just bumbling around in the dark hoping to stumble back into what they once knew. Scientists are prone to the first fallacy and the second is rife among religious folk. As a medical doctor who turned to siddha yoga (a form that puts a great deal of belief in superpowers and magic), Chaudhary had a rough road to not fall into one of these fallacies and, in my opinion, she falls more into the second — sounding at times like the ancient yogis knew more about the subatomic world and consciousness than science ever will. Most of the time, she words statements so that a careful reader can recognize what is well-supported and what is speculative, but she’s rarely explicit about the degree to which speculations are such, and I don’t remember an instance in which she presented an alternative that would undermine her argument. (i.e. The unstated argument seems to be that mantra is special among practices, that its usefulness is embedded in the fundamental physical laws of the universe, and, therefore, that it works by mechanisms unlike other meditative / complementary health practices [i.e. by engaging the parasympathetic nervous system so the body can make repairs using established biological mechanisms.])

In a nutshell, there is a “god in the gaps” approach to the book that says, look we don’t understand consciousness or all the “whys” of quantum mechanics, ergo there must be supernatural explanations. I don’t think that because we’ve used EEG since the 1920’s and fMRIs since the 1990’s and still haven’t yet unraveled the hard problem of consciousness that we need to say that god / supernatural forces are where we must look for explanation. The gap is ever closing, slowly but surely, and there’s no reason to believe it’s reasonable or useful to cram commentary from Vedas (or any other scriptures) to fill the gap.

It’s not only the science where Chaudhary presents a belief as though it is established truth without alternative explanations. Early on, she states that colonization is the reason for the decline of meditation in India. Don’t get me wrong, I’m as accepting that colonization resulted in a great number of evils as anyone, but it’s a leap to say that – therefore – every negative a society faces is because of its colonizer. I would point to Thailand, a society that was never colonized (except a brief period by the Burmese) and which is primarily made up of Theravadan Buddhists (a system for which meditative practice is considered central,) most of whom also do not meditate regularly today. I suspect a more logical explanation for the fact that most Indians don’t meditate today is that: a.) it’s hard work and time consuming (as a productive endeavor it’s not bread-winning and as a leisure time activity it’s laborious,) and b.) the majority of Indians (like the majority of Thais) probably never mediated. (When we look back in time, we often want to create this wholesome and uniform image that what we have writings about was how everyone lived, and that probably never reflects the truth.)

So now that my rant is over, I should say that I didn’t think this book was horrible, by any means. It has a lot of good information, and some of the speculative bits offer interesting food for thought. As long as one reads it carefully and with a healthy dose of skepticism, it’s a beneficial consideration of sound and vibration in health and well-being. It’s just that when I compare it to, say, Davidson and Goleman’s “The Science of Meditation” (which I reviewed recently) this book is far less careful about presenting the science, eliminating pseudo-science, and letting the reader know what is controversial and speculative versus what is well-supported by sound and rigorous investigation.

5 Non-Yoga Video Channels that Are Great Resources for Yoga Teachers

As I’ve been expanding my pranayama (yogic breathing exercises) practice, I’ve found myself searching beyond traditional yogic sources of information at times. It turns out that there are several disciplines from which valuable tidbits of information about breath can be gleaned, including: martial arts, freediving, and physiology.

As I was on a freediving site (shown below, #5) learning some lung capacity expanding exercises, it occurred to me that it might be beneficial to do a post of some of the sources of information that I’ve found useful that wouldn’t necessarily be stumbled upon by those looking for information on yoga.

5.) Adam Freediver: This enthusiastic and whimsical Aussie freediving champion offers fascinating tips on respiration — many of which are of use out of the water as well as in.

4.) Physical Therapy Video: Bob and Brad, Physical Therapists, offer advice and exercises that may be helpful for students with hyperkyphosis (excessive back rounding), duck foot (excessive external rotation of legs), or a number of other common postural / bodily challenges.

3.) SOLPM (The Science of Learning Power Move): This site offers progressions and capacity building exercises that will help one with challenging exercises, e.g. handstands, that most people can’t do without a gradual building up. As with the Adam Freediver channel, not all of the videos are relevant, but a number of them are.

2.) Crash Course:: This witty educational channel presents excellent graphics and a light-hearted and watchable commentary by Hank Green (one of the Vlog Brothers.) The Anatomy and Physiology Series is particularly relevant, but there are select videos in other series — such as Mythology — that one may find illuminating.

1.) TED Talks: Unless you’ve been living under a rock, you’re probably familiar with TED, but you may not be aware of the breadth of topics they’ve covered, including meditation, biomechanics, yogic philosophy, breathing, and more.

Honorable Mentions:
Calisthenic Movement: Like SOLPM, this channel can help build up some of the challenging maneuvers, such as handstands, but you may also find out something useful about more rudimentary exercises, such as planks.

ASAP Science: This science channel that uses line-drawn graphics has some interesting and informative videos on topics such as meditation, hypnosis, and nutrition.

BOOK REVIEW: Perfect Breathing by Al Lee and Don Campbell

Perfect Breathing: Transform Your Life One Breath at a TimePerfect Breathing: Transform Your Life One Breath at a Time by Al Lee
My rating: 4 of 5 stars

Amazon page


It’s not an exaggeration to say that there is no set of yogic practices with a greater power to transform one’s life than breathing exercises (pranayama.) With this in mind, I’m always on the look out for new sources of insight into breathing – be it from free-divers, Buddhists, sports scientists, yogis, martial artists, or else-wise. This book provides an overview from a diverse set of experts with descriptions of a number of different breathing practices (e.g. Taoist qi gong, yogic pranayama, a practice for runners, etc.,) but it takes as its central tenet a six-second breath that it recommends as the titular “perfect breath.”

Breathing practices are often underestimated. People, after all, figure that they’ve been breathing every day of their lives, so who can teach them anything on the subject. The idea of reading a book on breathing is right up there with watching the paint dry or the grass grow for excitement. Unfortunately, in parts – many densely pack up front – the authors do too little to dissuade readers of this belief. In early chapters and sprinkled throughout, the book is rife with truisms and banal comments that will leave the rankest neophyte thinking they aren’t going to learn anything of value. That said, I’m glad I kept with it, because the authors convey some powerful insights by telling the stories of people from various walks of life who’ve achieved great things by improving their breath.

The book is organized around a central structure of breathing as a tool for improvement of body, mind, emotion, and spirit. This is sound approach to covering the topic, and the discussion of breath as a means to emotional control is particularly beneficial and welcome. It could be argued that the coverage of the topic of spirituality could have been jettisoned without much loss. The authors talked around the subject in away that was vague and insubstantial. To be fair, they may have been trying to avoid running afoul of individuals who were either secular / scientific (non-spiritual) or who had strong sectarian beliefs on spiritual matters.

The book has seven parts. Part I consists of two chapters that offer an introduction into the topic. These could have been pared down without substantial loss of value. Part II (Ch. 3 – 8) is entitled “Your Perfect Breath” and it discusses developing awareness of breath, body, emotion, spirit, and introduces the fundamentals of how one should breath the “perfect breath.” Part III (Ch. 9 – 12) explores the role that breathing practices can have on improving health outcomes. It’s well established that the body puts healing / rebuilding on hold under high stress, when the sympathetic nervous system is engaged. Breathing practices can help trip parasympathetic (rest and digest) activity. Part IV (Ch. 13 – 15) is of particular interest to athletes and those who want to perform better at some physical or mental activity. In addition to discussing both physical and mental performance, the authors devote a chapter to what is sometimes called Flow (Csikszentmihaly) or The Zone, and how breath can play into quieting the mind to facilitate said state. Part V (Ch. 16 – 19) is about breathing as a means to take control of one’s emotional life. People in the throes of emotional turmoil are unlikely to notice how that turmoil influences their breath, but it has a major impact — and it’s a two-way street, i.e. one can help mitigate excessive emotional response through breath. Part VI (Ch. 20 – 21) is devoted to spirituality and the nexus of breath and prayer or meditation. The final part (Ch. 22) explores the idea of the final breath. I thought this was a valuable discussion, given the tremendous anxiety of coming to one’s last breath and its impact on people’s lives.

There are no graphics in the book. They aren’t greatly missed, but might have been useful in places. (It’s probably more accurate to say the authors could have gone into more depth if they’d used graphics and not stayed in such vague territory.) There is an appendix that lists and briefly describes the included exercises, and the e-book / Kindle version includes hyperlinks to the detailed description in the book’s interior. Having a link to the practices is a useful feature. There is also a short section of recommended readings.

While it took me a bit of time to get traction in reading this book, once I did, I learned a great deal. I would recommend it for anyone who is interested in an overview of breathing practices for health, emotional control, and increased physical performance. The authors transmit expertise from a broad range of experts from various walks of life.

5 Considerations for Sun Salutations

Sun Salutations (i.e. Surya Namaskara) are a sequence of poses (asana) popular in Hatha Yoga for warming up both the joints and the core — among other reasons. There are a number of variations on this practice. The version I demonstrate in the video is common, and is often associated with Swami Sivananda. Below are a few points for consideration.

5.) Don’t forget the quad when in the Lunge (Ashwa Sanchalanasana): While stepping back and forward into the lunge position (ashwa sanchalanasana), sink the thigh of the backward extended leg down to get a stretch in the hip flexors and quad. This is commonly glossed over, missing a good opportunity. Secondary note: look forward in the lunge or at least not back and down between the legs (the latter suggesting excessive rounding of back.)

4.) Lift up into Plank (Utthita Chataranga Dandasana): If you have a valley between your shoulder blades, engage the serratus anterior, lift the torso up away from the floor, and turn that valley into a small, gentle-sloping hill. In other words, try to get the shoulder blades to come further apart.

3.) Place the ankle under the knee in the return Lunge (Ashwa Sanchalanasana): This is a challenge for many students depending upon a range of factors from flexibility to thigh girth to waist girth. It’s better to put the back knee down and use your hand to pull the lower leg into place than to try to stand up with the knee considerably forward of the toes. The latter puts a lot of load on connective tissues rather than transferring it down the length of the shin into the foot and floor.

2.) Keep hips up in “Knees-Chest-Chin-Down” (Ashtanga Namaskara), if you can safely do so: This is another challenging one for many students, particularly given the common nature of thoracic hyperkyphosis (i.e. excessively rounded upper back.) If one does have hyperkyphosis, one doesn’t want to force the matter. However, this does counteract that forward rounding tendency by stretching tight muscles out.

1.) Keep shoulders down and away from ears in Cobra pose (Bhujangasana): Unlike the previous common errors, this one seems to come down to lack of awareness or effort as much as it does to physical limitations. Of course, thoracic hyperkyphosis can also make Cobra challenging because the spine wants to bend the other way. I see students who have trouble keeping their navel on the ground and their arms bent because they have an almost “S” curve in their backs.

BOOK REVIEW: The Healer Within by Roger Jahnke

The Healer Within: Using Traditional Chinese Techniques To Release Your Body's Own Medicine *Movement *Massage *Meditation *BreathingThe Healer Within: Using Traditional Chinese Techniques To Release Your Body’s Own Medicine *Movement *Massage *Meditation *Breathing by Roger Jahnke
My rating: 4 of 5 stars

Amazon page


This book examines how four techniques – movement, massage [specifically, self-applied], breathing exercises, and meditation — can be used to facilitate a robust immune system and to stimulate the body’s innate healing capacities. Jahnke, as a Doctor of Oriental Medicine, specializes in Traditional Chinese Medicine (TCM,) but he acknowledges that these activities aren’t the exclusive domain of that system. The book is designed to be one-stop shopping for an individual seeking to build their own self-healing practice either as preventive medicine or as a part of one’s treatment regimen for an ailment or infirmity.

The thirteen chapters of the book are divided into five parts. The first two chapters form the book’s first part, and they discuss the body’s innate healing capacity and the literature on the roles of mind and self-applied activities on health outcomes.

Part II forms the heart of the book, and it consists of chapters three through seven. Chapter three offers insight into the process of building a personal practice from the four key activities including guidelines for how to organize disparate parts into a whole and how to fit it into one’s life overall. The other four chapters provide examples and techniques for each of the four components of the system: gentle movement (e.g. qiqong), self-applied massage, breathing exercises, and meditation and deep relaxation techniques.

Part III expands on the issues touched upon in Chapter 3. That is, it explores in greater detail the nature of building and deepening a personal practice.

Part IV, entitled “The Way of Nature,” provides a philosophical context for a global self-healing movement and describes how a community can be built around this endeavor. There are three chapters in this section. The last part consists of only one chapter and it describes a potential future self-healing regime. Throughout the book there is a recognized that, while modern medicine is invaluable, it’s also developed a dysfunction by undervaluing the role of the body’s innate healing factor, while not only removing the patient from of the driver’s seat but also stuffing them in the trunk as a sort of cargo in the health and healing process.

The book has line drawings to help clarify the techniques. There are several pieces of back matter (an appendix, a bibliography, and a resources section) to help make the book more useful. [The appendix is a little strange and unfocused for an Appendix. It’s almost more of a Reader’s Digest Condensed Version for someone who wants to get to brass tacks, but it does offer some interesting insight into how a community built around these ideas has formed.]

I found this book to be informative and believe it offers a great deal of valuable insight into how to not only develop one’s own preventive medicine activities, but also how to situate those activities within a community of like-minded individuals. I thought the author did a good job of presenting scientific evidence for building a self-healing practice while not becoming too bogged down technical detail and offering a way of thinking about it for those who look at such activities in more metaphysical or spiritual terms. I’d recommend this book for anyone who is considered engaging in health enhancing activities.

5 Reasons to Practice Yang Style 24 Form

With slight variations, this taijiquan (tai chi chuan) sequence is alternatively called: Yang Style 24 Form, the Yang Style Short Form, Beijing Standard Form (occasionally Peking Standard Form), or Simplified 24 Form. Here are some reasons to give it a try.


5.) Widespread: It’s the single most popular taiji form in the world. This means, if you’re the gregarious type, you can join groups in parks all over the world.

4.) Balance: It’s good for your balance and you don’t want to fall and break a hip.

3.) Moving Meditation: It’s a great way for fidgety individuals to work up to meditation. All the meditation without having to stay perfectly still.

2.) Scalability: It’s scalable to fitness level. Because taiji is popular with older people, many modifications have been developed for those who aren’t ready for the classical expression of the form.

1.) Gentleness: There’s virtually nothing to go wrong — as long as you “know thyself.” i.e. There are no contraindications, at least for the simplified form.

BOOK REVIEW: T’ai Chi Classics by Waysun Liao

T'Ai Chi ClassicsT’Ai Chi Classics by Waysun Liao
My rating: 5 of 5 stars

Amazon page


This book conveys the teachings of three tai chi masters of old: Chang San-feng, Wong Chung-yua, and Wu Yu-hsiang. However, those masters’ treatises take up only a small portion of the book. That’s not a criticism. No doubt the treatises were cryptic and sparse, and so they are presented with commentary embedded rather than as literal translations. The treatises discuss the concepts that each of the masters thought was essential to the art, and the author conveys these complex and ethereal ideas in a way that is as understandable as possible.

Before presenting the three treatises in chapters four through six, the author offers a three chapter background on essential concepts for the tai chi student to understand. Chapter 1 presents historical background on tai chi and differentiates temple style from the family styles of tai chi, as well as giving insight into the philosophical underpinnings of the art. The second chapter offers a primer on chi, the life-force energy that is at the conceptual heart of tai chi. Chapter 3 describes jing and the means by which chi is expanded and transferred.

After the three treatise chapters, there is a final chapter that is intended to take the book from theory to practice. Most of the final chapter is a step-by-step description of a tai chi form, and consists of line drawings of the positions with bullet point descriptions of the movements. However, the chapter begins with some lists of key philosophical concepts as well as clarifying ideas about movement fundamentals.

There are line drawings throughout the book, not only to show physical positions in the practice but also diagrams to help convey the difficult concepts discussed throughout the book as well as Chinese calligraphy characters. Besides the calligraphy, these graphics are crude, looking as one might expect in a notebook. I don’t think the crude form of the graphics is a problem, and the notebook effect it creates may be an intentional aesthetic. As I don’t believe one can learn a martial art or other system of movement from a book, the fact that the graphics don’t offer much detail isn’t a problem.

I found the book to be thought-provoking and would recommend it for students of tai chi and qi gong.

BOOK REVIEW: Taoist Yoga & Chi Kung by Eric Yudelove

Taoist Yoga and Chi Kung- For good health,better sex,and longer life.Taoist Yoga and Chi Kung- For good health,better sex,and longer life. by Eric Yudelove
My rating: 4 of 5 stars

Amazon page


This book was originally released under the title: “100 Days to Better Health, Good Sex & Long Life.” It offers a 14 week qi gong practice that proposes to improve health, sex life, and longevity. It’s presented as a step-by-step explanation of the practice aimed at those who intend to carry out the practice—as opposed to those who are looking for a more general explanation or overview.

The book offers a systematic presentation of the 14 week / 100 day practice. It’s divided into two parts. The first is a short explanation of Taoist concepts as they pertain to health building practices, and particular emphasis is given to the concepts of chi (energy / breath), jing (body), and shen (mind.) That emphasis is valuable as each of the chapters (i.e. the description of each week’s practice) is outlined according to these three concepts. So, each week there is a new breath practice, new bodily practices, and a new meditation or visualization practice. That said, these practices build on each other—i.e. starting with very basic activities and either adding to them or shifting to more complex variations.

The sections on breath and mind are fairly straight forward and mostly involve one practice each per week. Those practices become quite complex over the course of the book, but it’s one practice per week. This is in contrast to the middle section that has three or four subsections of activities per week. The middle section on Jing, or body, includes subsections on making sounds, self-massage, “sexual kung fu” (exercises intended to tone the reproductive system and prevent chi “leakage”), and the movement exercises that one might most closely associate with qi gong (chi kung.)

The book has many graphics in the form of line drawings used to clarify anatomy or how one is to visualize the practices. There is a glossary to help explain both Chinese terms and terminology in English that is specific to qi gong. There is also a two page bibliography that includes many works by one of Yudelove’s teachers, Mantak Chia, but also including works by individuals from other lineages and systems.

I have practiced through week eight. One may find the parts of the practice vary in their usefulness, but there doesn’t seem to be any harmful practices and there are many from which one will benefit. I’d recommend the book if one is looking for practices—as opposed to background. The explanations are systematic and the overall practice is well-organized. It’s not the kind of book that is much of a pleasure to read for reading’s sake. Much of the book is lists and bullet points of step-by-step explanation.

For centuries there have been cases in which a change in diet –often accidental– led to relief from a mental illness. However, given the sporadic nature of such effects and the complete lack of understanding of microbes, the enteric nervous system (i.e. the gut’s own “brain” that communicates with — but is also autonomous of — our “first” brain,) and the complexity the symbiotic relationships involved, these anecdotal cases had limited influence on the state of medicine. However, recent years have seen an explosion of understanding in this domain. This has resulted in a vast number of books being written on the role of microbes in the gut for overall health, the role that changing diet can have on changing our microbiota, and related topics such as how the overuse of antibiotics can have a deleterious effect on health by tossing out the microbial baby with the bath water. This book touches on all those topics (and more) as it explores the role of our bacterial hangers-on on our mental health.

The book consists of nine chapters. The chapters are organized so as to first present one with the necessary background to understand how changes to one’s gut microbiota can improve one’s health —particularly one’s mental health (though many of the mental illnesses influenced by microbiota are linked to physical ailments)— before moving on to the specifics of what microbes have been shown to have a given effect and what diseases can be influenced by consumption of probiotics.

The first five chapters give the reader an introduction to the topic and an overview of information one needs to know to understand the later chapters. Chapter three gives one an overview of the changing profile of one’s microbiota over the course of one’s life. Particular emphasis is given to one’s youth and to the transfer of bacteria to infants. [Readers may be aware of the problem that c-section births result in a failure of babies to receive a dose of beneficial microbes imparted by passage through the vaginal canal.] Chapter four takes one on a quick ride through one’s alimentary canal from mouth to rectum, with particular emphasis on questions such as how bacteria survive the stomach’s acid bath, and which parts of the digestive system contain which microbes (and to what effect.)

The last four chapters dig deeper into the specifics. These chapters look at specific probiotics, how one can get them into one’s system, and what science has found out about probiotics and psychobiotics (like probiotics, but specifically ones that influence mood and mental states) effects on specific ailments. Chapter eight, which deals with major diseases, does cover physical ailments as well as mental ones because – as mentioned— these afflictions often go hand-in-hand. The last chapter (Ch. 9) looks at where this body of knowledge is going. It delves into practices that are presently well-established, such as fecal matter transplants, but also into challenging works-in-progress such as attempts to develop narrower spectrum antibiotics so that we can get the life-saving benefits of these medications without their crippling side-effects.

The book has many graphics, as one would expect from a work that investigates such a complex scientific topic. I can’t really speak to the quality of the graphics as the review copy I read didn’t have completed graphics. However, the subjects of the graphics seemed appropriate and well-placed. The book also has a glossary, annotations, and a further reading section to assist the reader in the study of this subject.

I found this book to be informative and engaging, and would highly recommend it for anyone interested in the role of microbiota on mental health. The text was well-organized and readable. Given the scientific nature of the material, it’s easy for such a book to become ponderous, but the authors made attempts to keep the tone light and the presentation non-intimidating.
