B12 and B6 Vitamin Supplementation Linked to Cancer in New Study
Brett Black replied to Brett Black's topic in General Health and Longevity
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. -

Do you floss? If it's for dental health, you needn't bother.
Brett Black replied to TomBAvoider's topic in General Health and Longevity
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: -

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- 34 replies
