Got an interest as a couple of my old mates went on to do triathlons+ironman stuff that work the heart consistently at high rates. Both stopped when they started sensing bad juju, also Greg Welsh going through endless heart surgies was a bit of a wake up call. Seems doing cardio intense activities will highlight any underlying issues. I rode with a bloke who use to do 3-400km a week for 10-15yrs, insanely fast rider to keep up with but ended up with a pacemaker installed in his early 40s. Possibly genetics, possibly wore out his heart!
www.triathlete.com/culture/from-the-heart/ It's as though people don't understand that iron carries oxygen through blood, calcium also travels through blood, calcium and iron form an industrial abrasive.
I have iron oxide in my blood??

I bloody hope so


Worst Dad pun today. (Not sure if you were being serious. I thought not, but just in case haemoglobin:
en.wikipedia.org/wiki/Hemoglobin)
It was sort of a joke in that just having iron in your blood and oxygen in your blood, does not necessarily make it iron oxide in your blood. Psychoejoe's approach seems to suggest everything just all combines, which I doubt it does. I just scanned the wiki entry and I am still not sure if there is iron oxide or not. I don't think so though. I can't imagine that a reaction of that type could occur in the human body and then be readily reversed to release the oxygen.
Last week I tried to donate plasma again. My haemoglobin is always high. They used to call it 'iron level' and now they call it haemoglobin level. The annoying thing last week was that my plasma turned red, in that the red blood cells got into the plasma through the filter. Apparently when something is not quite right with the machine, the red blood cells can break and sneak through the filter. Ruining the plasma donation and making it a bit of a waste of time. So, yes, I understand what haemoglobin essentially is and the colour

Yes you are right, it's not iron oxide that gets Twiggy excited, but the oxygen does bind at the ferrous atom.
As for K2 I first heard of it in a dental publication as it turns out a Canadian dentist was the instrumental in its discovery. Here is an neat little summary of his travels:
"...mild-mannered Dr. Weston Price, a Canadian with a small dental practice in Ohio, wondered why so many of his patients had terrible teeth. He hypothesized that there was something about the rapidly modernizing diet that was linked to declining dental health. Dr. Price sought out pre-industrial populations scattered across the globe in an effort to study this relationship between tooth decay and nutrition.In a series of perilous expeditions, he made his way to remote villages in the mountainous pockets of Switzerland, settlements along the rugged coasts of the Outer Hebrides, and the archipelagos of the South Pacific. He travelled with the nomadic Masai of Tanzania and the Nuer of the South Sudan, New Zealand Maori, the Inuit of Alaska and the tribes of the Peruvian Amazon and Andes. He observed that populations that maintained their traditional diet did not suffer from the tooth decay or malocclusion that was rampant back home. Instead, he found square jaws with neat, straight rows of teeth. When the same families were introduced to common processed foods, they would develop cavities and dental decay. Armed with a camera, he would take photos of siblings - where the older child was raised on a traditional indigenous diet and the younger living on imported foods. Where the first child would have well formed dental arches, the second would have many misaligned teeth.
It was a predictable pattern, and in addition, Price noticed several other symptoms of declining health, such as slow healing bone fractures.His fieldwork throughout the 1920s and 1930s yielded over 15,000 such stark photographs. When he returned, he detailed his ethnographic and nutritional studies in a book called Nutrition and Physical Degeneration. Without the benefit of our understanding of modern nutrition, Price hypothesized that these declines in dental health were not the result of some toxin in American diet, but the "absence of some essential factors". He tested and analyzed thousands of samples of traditional foods for their nutritional content and compared them to common foods of the time. What he found was that many of the traditional foods, like fish eggs and the butterfat of grass-fed cows, were rich in fat-soluble nutrients. He deduced that there was some activator or catalyst in the fat-rich diet that allowed the body to make use of other macronutrients like minerals. One activator had a significant affect on the health of bones and teeth, but since he could not identify or chemically isolate it, he labelled it as Activator X.For years, physicians and nutritionists debated what this mystery Activator X could be. Some thought it might be a kind of essential fatty acid like EPA. Sixty years after Activator X was first mentioned, researchers now believe Activator X to be vitamin K2."
