If nanotubes exist in car exhaust and buckyballs in candle soot then we've already performed a huge experiment on loads of people.
Life expectancy is still increasing...
- sitkack 11y agoLife expectancy is a really poor metric. When accounting for the average life expectancy due to huge drop in infant mortality, LE has made very low gains at a high economic and medical cost. I was commenting that if naturally occurring nanoparticles as created in combustion are getting lodged into tissue, that synthetic nanoparticles have the same opportunity. Combustion byproducts are already known carcinogens.
- Houshalter 11y ago"every mouthful of food you and I have ever taken contained many billions of kinds of complex molecules whose structure and physiological effects have never been determined—and many millions of which would be toxic or fatal in large doses. We cannot doubt that we are daily ingesting thousands of substances that are far more dangerous than saccharin—but in amounts that are safe, because they are far below the various thresholds of toxicity. But at present there is hardly any substance except some common drugs, for which we actually know the threshold." E. T. Jaynes
- unclebucknasty 11y ago>life expectancy is still increasing...* Yet cancer, Alzheimer's, autism, etc. are on the rise.
- domas 11y agoBecause we are better at diagnosing them then years ago. It does not mean that there are more cases of "cancer, Alzheimer's, autism, etc.". People diagnosed with Asperger syndrome would be called quirky, or plainly weird twenty years ago.
- unclebucknasty 11y agoNope. Doesn't explain it away. Real rates are rising.
- hugh4 11y agoCancer and Alzheimer's are on the rise because life expectancy is increasing.
- unclebucknasty 11y agoNope. That only explains a portion of the increase.
- hugh4 11y agoGot a convincing and well-sourced statistical argument on that one?
- unclebucknasty 11y agoYes. Do you for your declaration?
