    In my experience it's uncommon to find B12 tablets less than 100µg, which is over 40 times the RDI and almost twice the dose shown in this study to be linked to a doubling of lung cancer risk. My impression is that 1000µg B12 tablets may actually be the most commonly available dose - over 400 times the RDI. So it wouldn't surprise me to find people taking such doses.

    - Some media articles interviewing an author of the new study and also referencing previous studies showing links between B12 and B6 supplementation and cancer: https://www.sciencedaily.com/releases/2017/08/170822175515.htm https://www.theatlantic.com/health/archive/2017/08/b12-energy/537654/

    Some studies examining the evidence(or lack thereof) for routine 6-monthly dental check-ups: --- ---

    Sure, that may be a possibility, but obviously it's speculation. My past reading on these and related issues suggested to me that there is a lack of quality evidence surrounding common dental hygiene practices in general. Thus speculation and hypothesis may be necessary guiding forces unfortunately. If I recall correctly, other comments on the Longecity thread mentioned bacteremia resulting from teeth brushing and even eating. So bacteremia induction may not require unusual/unaccustomed gum stresses. Of course, even if bacteremia is a common daily occurence resulting from everyday living, that doesn't mean it's desirable. Here's a study that showed bacteremia from toothbrushing alone, with powered toothbrushing inducing more bacteremia than manual toothbrushing:

    This meta-analysis concludes that there is a lack of scientific evidence to support routinely recommending flossing:

    Flossing may cause gum tissue trauma leading to oral bacteria transmission into the bloodstream ("bacteraemia"):

    The Ultimate Purpose of Life

    Brett Black replied to Dean Pomerleau's topic in Chitchat

    Who says the meaning/purpose in my(and your?) life is "merely" "subjective" "arbitrary" "preference"? My meaning, all meaning, is part of the very fabric and essence of existence. And, I am, after all, existence itself. Claiming any of this is arbitrary, assumes that there could be some alternative way things could be - but this is nonsense. What is, is what is - end of story. No imaginary God could claim any greater. It's kind of pathetic to see how self-denying...self-negating...most everyone is. Like a bunch of sick ascetics or something. Are you all gonna start whipping yourselves soon too? I suppose it's an outgrowth of social control. Now God's gone, society has had to fashion a new method to maintain control: the postmodern "that's only your opinion!" to keep people in line works nicely. The ultimate in low self-esteem is hammered into you - you can't even trust your own meaning, purpose, LIFE. Ha! No thanks - I retain my godhood. Furthermore: egoism combined with empathy can combine to form something like Peter Singer's "Point of View of the Universe" - there need be no contradiction there. I feel your pain, and because I don't like being in pain I don't want you to be in pain. Simple. Empathy aligns with the apparent reality of other beings' capacity to feel pain/pleasure, making empathy an accurate, instinctual-level, representation/reflection of reality. Then, right = pleasure and wrong = pain. "Right" and "wrong" being more complex manifestations/representations of pleasure/pain.

    Why Don't UK Vegans/Vegetarians Live Longer?

    Brett Black replied to Dean Pomerleau's topic in General Health and Longevity

    The lack of mortality benefit seen in the EPIC-Oxford vegetarians/vegans might be due to bias from the "healthy volunteer" effect among the non-vegetarians/vegans. It looks like the vegetarians/vegans still managed around half the expected death rate of the general population[1]: --- Dean, do you know about www.veganhealth.org? It's got to be one of the best science-based websites relating to veganism. Here's a veganhealth.org page that collected mortality data of vegans from several studies: http://www.veganhealth.org/articles/dxrates

    So Why Don't We Brew Our Chocolate?

    Brett Black replied to Dean Pomerleau's topic in CR Practice

    Do you eat rice or rice-derived products? There have been some concerns raised about arsenic levels in rice, e.g.: http://www.consumerreports.org/cro/magazine/2012/11/arsenic-in-your-food/index.htm
