“…the fact remains that, around sixteen months ago, my cognitive score was 34/100 and now it’s 87/100.”  –  Lea N, Batemans Bay, NSW

Are you worried about Dementia – but think there’s nothing you can do?

You have good reason, especially if you’re a woman. Dementia is the #1 killer of Aussie women and #2 of Aussie men yet many experts now say that up to 90% of cases can be prevented. Others say it can even be reversed – and Lea says she’s proof of that.

In this easy-to-read, plain English, 107-page guide (for tablet and desktop but not smartphone) – that pools 500 expert opinions from around the world – discover how:

  • Dementia isn’t normal ageing & you don’t have to get it;
  • The real causes of dementia are very close to home;
  • New dementia drugs may do you more harm than good;
  • Lifestyle changes are your safest bet to prevent, even reverse it;
  • You can cut your dementia risk by taking 11 practical steps.

Kim Brebach is a veteran information researcher & technical writer. He’s also a baby boomer & passionate cook.

Over decades working in IT, BioTech & MedTech with companies like Silicon Graphics, Novell & Roche Diagnostics, Kim researched & wrote hundreds of papers to make complex concepts easy to understand. Many say they’re a joy to read.

In the 90s, Kim’s first wife developed emphysema, a terminal disease. Searching for ways to ease her suffering, he discovered troves of health & medical research that none of her doctors seemed to know about. Much of it was about preventing disease, rather than trying to cure it once it had taken hold. After her death, Kim kept his finger on the pulse of preventative medicine research.

30 years on, Kim translates the latest disease prevention research into short, snappy, highly-readable guides. They’re focused on the diseases that keep boomers awake at night – dementia, cancer, heart disease and diabetes – with the ‘anti-diet’ as a bonus. Showcasing skills honed over decades, Kim transforms dry research into engaging ‘who-done-its’. Science has never been so enjoyable to consume.

Kim’s not a health or medical expert but he’s found thousands who are – and provides direct links to them all in his eBooks. You can read Kim’s full story here.


Muscles & Marbles was created for Aussie boomers like you – by two other Aussie boomers, Kim Brebach & Tracey James. It’s the place where you can learn to thrive for much longer.

Muscles & Marbles is where you’ll find cutting-edge health and medical research from around the globe, translated into everyday, often entertaining, English. Mostly, it’s about preventing the chronic illnesses that hold most boomers back – and revelling in ways to live life to the full.

It’s the place for you if you want to understand the latest science – so you can ask better questions and make better-informed decisions about your life.

There’s no other website like Muscles & Marbles.

  1. L Nelson

    When I told my doctor I had managed to reverse most of my symptoms, he didn’t believe me, so I am thrilled that you have written a book on this topic. A major barrier is neuropsychologists and medical doctors who fail to point people in the right direction because they’re still following 20th century medicine.

    • Tracey James

      Thank you, Lea, for your inspiring words. It is fantastic to hear of your success.

  2. Patricia G

    Thank you for all the extensive information that’s easy to access – and I really do enjoy the song titles! Working my way through, great to see the 11 points, already nailing some. Presently looking into the salmon situation now I won’t be buying Tassal.

    • Tracey James

      Thank you, Patricia. We recently found NZ King Salmon fresh and it was sensational. Only problem was, it didn’t taste like Alaskan wild caught; more like TasSal which is worrying. I hope the Kiwis aren’t following Aussie salmon farming practices now. We’ll dig into it.

  3. Karen B

    Well done you for sifting through the bulls**t to present a more balanced view and recommendations. Thank you also for the “wake up call” which I will embrace! I am now going to pass this book to my husband (almost 68) who I think could very much benefit from this informative read.

    • Tracey James

      Thank you, Karen. We’re glad you like the approach and good luck with Hubbie!

  4. Ros W

    Thanks for making so much information (and misinformation!) about dementia, its causes, cures, and prevention, much more digestible. So much to take in! Linking it to dementia studies has been very helpful. Prevention is clearly better than cure… since there isn’t one.

    • Tracey James

      So glad you found the eBook helpful and digestible – and for sharing this feedback with others. We really appreciate this, Ros.

  5. Megan F

    Thank you so much for this guide. With every page I read, I felt more and more relieved.

    • Tracey James

      Thank you, Megan. So glad you feel this way and are happy to share it.

  6. Julie S

    This guide is astonishingly well researched and referenced. To get this all in one place is priceless.

    • Tracey James

      So glad you think so, Julie, and thank you for sharing it with others.

  7. Gayle

    Very easy to read, well researched, understandable. Treats a hard subject sensitively. The customer assistance is wonderful as well.

    • Tracey James

      Thank you, Gayle, we are thrilled that you think so. Made my day!

  8. Karen M

    I’d been worried about things I’d heard but couldn’t confirm. It’s so helpful to have all this research in once place. One question, though, how will you keep it all up to date?

    • Tracey James

      Hello, Karen, thank you for your feedback! Re updates, we’re thinking about making the eBooks ‘read online’ rather than ‘download & read’. This will negate any download issues and ensure that everyone has the latest version at purchase – and later for a second or third read.

  9. Pamela

    I found the book us very good. I havent digested all of it yet, but I am finding it very helpful.

    • Tracey James

      Thank you, Pamela. We really appreciate your taking the time to tell us.

  10. Julia

    The booklet was great, informative, accurate and inspiring.

    • Tracey James

      Thank you, Julia. That’s really great to know and exactly what we hoped for!

  11. Alison Bassat

    I mucked up downloading the e-book and emailed for help. Couldn’t believe it when Tracey called me back and walked me through it.

    • Tracey James

      My pleasure, Alison. We love a bit of old-fashioned service, too!

  12. Marion Fogarty

    I’ve never found health research so easy to read, understand and apply. I’m telling all my friends about Marbles.

    • Tracey James

      That’s terrific to hear, Marion. Thank you.

  13. J Forrest

    I found some of the causes of dementia a bit hard to swallow. If we can prevent so much of it, why aren’t doctors saying so?

    • Tracey James

      We hear this a lot, John. We think it’s because GPs don’t have time to keep up with all the preventative research for chronic illnesses. Even if they did, they’re probably not set up to advise, monitor and follow up, as researchers who specialise in dementia research can. If you’d like to explore further, please email kim on He’d love to hear from you.

  14. Abigail P

    This dementia e-book is amazing, well shocking really, but I think we need to be shocked about what we’re not being told.

    • Tracey James

      Thank you, Abigail. We found it pretty shocking too, which is why we wanted to let others know.

  15. Reg M

    This is a well researched and informative guide for those wanting a better chance of a healthier, longer life. We owe it to ourselves to be better informed about what we can do to avoid dementia. This guide provides the means.

    • Tracey James

      Thank you for this comprehensive feedback, Reg. Very glad you feel this way.

  16. Ian Reynolds

    Dementia isn’t exactly a fun topic but you made it short, sweet and, surprisingly, enjoyable to read.

    • Tracey James

      Thank you, Ian. Kim will love to hear this. He puts a lot into making tough topics easy to digest.

  17. Sue Mack

    I was blown away by that doctor saying that 90% of dementias can be prevented. Why isn’t my doctor saying this?

    • Tracey James

      Thank you, Sue; we wondered this, too. It seems that prevention is hard to explain, implement and monitor and most doctors aren’t set up to do it – or dementia research. That’s why those specialists who can do both are the ones who publish in journals.

  18. Susan G

    Every baby boomer needs to know this about dementia. We don’t have to be sitting ducks.

    • Kim Brebach

      Thank you, Susan. So glad you feel that way. It was a revelation for us, too.

  19. Connie Vanderbent

    Now I feel I don’t have to wait for a Dementia drug. I feel empowered and I’m definitely telling my friends about this ebook.

    • Tracey James

      Thank you for sharing how you feel, Connie. We’re told that the wait for an effective drug could be a long one.

  20. Marilyn L

    I’m astonished that so many dementia experts are saying prevention is possible. I feel much more in charge now.

    • Kim Brebach

      We were surprised, too, which is why we kept digging. Thanks so much for sharing your thoughts.

  21. Andre Solles

    Your use of song titles and stories is brilliant. It reminds me that you’re a boomer, too, with a life-story running concurrent to mine.

    • Kim Brebach

      Thank you, Andre. I was worried they might seem frivolous.

  22. Pete

    I found this book extremely informative, very easy to read and not too long. I have gladly recommended it to friends.

    • Tracey James

      Thank you for sharing this feedback, Pete. Especially glad you found it easy to read. Dementia isn’t a simple topic.

  23. Eva J

    Having lived with my mother’s decline due to dementia, I am keen to avoid the same fate. I found this book very readable, with easy to follow strategies and the links to current research very thought provoking.

    • Tracey James

      Thank you for this very insightful feedback, Eva. Very much appreciated.

  24. Mary Bolton

    I was amazed by the number of references links. It was reassuring to mouse over to check the source, click to read it, then click back to keep reading.

    • Kim Brebach

      Thank you, Mary. Direct links made the ebook harder to do technically, but I hoped readers might find them reassuring.

  25. Marianne M

    Dementia is a serious topic and, although I can see why you used them, I found the song titles and excerpts a bit distracting.

    • Kim Brebach

      Thank you for your feedback, Marianne. I’ll take a look at this in the next review and see if I can improve the balance.

  26. Barbara Burke

    At 76, I am the lucky one who has lived more than my three score years and ten and still going strong without dementia. I am following your 11 points which are happily decreasing my waistline and belly fat and, I’m sure, helping my brain to not shrink or lose pieces of the jigsaw puzzle. PS: I found KEEP YOUR MARBLES a hard read, having two loved ones and a long time best friend on the dementia slide – but I think everyone needs to know what you’re sharing.

    • Kim Brebach

      Thank you for this comprehensive feedback, Barbara. It is greatly appreciated and very useful. Keep going strong!

  27. Martin White

    I was reluctantly persuaded by the research but have a nagging question: why aren’t our doctors talking about how to prevent dementia?

    • Kim Brebach

      Thanks for asking this, Martin. I was mystified, too, until I realised that prevention is hard to explain to patients and to implement and monitor, too, so most doctors don’t do it. Few are set up for it or for dementia research, anyway. That’s why those specialists who can do both are the ones who publish. If you’d like to discuss more, please email me directly:

  28. Tony Vanderbent

    Easy to read, not too long, with references accessible if you want them. No bull and, most importantly, very relevant in these times of decreasing health of body and brain.

    • Kim Brebach

      Thank you, Tony. So glad you found it useful.

  29. Jo Sommers

    The lifestyle changes seem doable even for me. I’m more conscious of the risks of developing dementia but feel I have ways to reduce them now.

    • Tracey James

      That’s really good to know, Jo. Thank you.

  30. Jil Swinnerton

    I’ve been saying for years that fat isn’t the enemy, so thanks for agreeing with me, Kim!

    • Tracey James

      Thank you, Jill. Isn’t it great that we can enjoy those good things we banned years ago, without a worry?

  31. Carolyn Brommley

    The personal anecdotes made this information-rich ebook lighter and easier to digest.

    • Tracey James

      That’s wonderful to hear, Carolyn. We were worried that including our own stories might be a bit cheeky.

  32. Cathy Gibson

    I think this e-book is brilliant. I’ve learnt many new things, confirmed that my husband’s and my lifestyles are mostly on track, and how to fix the others.

    • Tracey James

      So glad you think so, Cathy. Thank you.

  33. David Gray

    Some of the data was a bit hard to digest, even with the conversational approach, asides and explanations.

    • Tracey James

      Thanks for this feedback, David. We’ll look into this in our next review.
