Earlier quoted context omitted.

And is that nonsense or is there evidence that backs it up?

FYI: https://www.nih.gov/news-events/nih-research-matters/fasting... But as to the mechanism... not a scooby.

> Long periods of fasting between meals helped male mice live longer and healthier lives, regardless of the content of their diets. More studies are needed to confirm these results and understand how different fasting periods may impact health.

Wow. I knew cities are polluted but this is extreme. In 50 years we might look at pollution as we look at smoking now, a terrible self-inflicted wound on civilization that took way too long to acknowledge and fix.

Proponents of fasting will love this, since the idea is that not eating for a while will cause the body to scavenge for this old / damaged cell material.

But here we want cells to eat themselves, not damaged organelles. I believe nuclear DNA isn't among the things cleaned up by autophagy.

Don't forget the fraud of the whole Dieselgate scandal.

We were all getting excess NO2 pumped out of diesel engines. Effectively shortening all our lifespans.

I have multiple relatives who are aging researchers.

Fasting is healthy and normal. Many humans historically regularly "fasted" by today's standards just by going 12+ hours between modest meals.

We know that it slows signs of aging, but it can also depress the immune system (which might be why it slows aging), so it can still cause you to die young.

The effects of fasting on all-cause mortality are generally positive, but it's unclear right now whether that means people need to do uncomfortable levels of fasting or if most of us are just killing ourselves with eating too much and too often.

Like bathrooms next to kitchens in roman plumbing, like lead pipes, like asbestos insulation, or like nonstick pans.

The course of history is full of misteps. Of course, an important distinction is that now we are all individually at varying ideological stages of incredulous reflection about these.

"The idea of taking a cancer-blocking pill if you live in a heavily polluted area is not completely fanciful. " - Prof Charles Swanton Really interesting and, obviously major news in the battle against cancer. In terms of research funding; wonder if it will lead to industries linked with cancer, e.g. tobacco, alcohol, motor vehicles ... , quietly starting to fund prophylactic R&D as well?

Win-win: No need to invest into changing life-threatening tech and make money selling the protection. Profits can only rise!

Yeah, I know very Jean-Baptiste Emanuel Zorg like ( https://www.youtube.com/watch?v=Ad_fdYFHYXo ).

Hard to argue that that is not where we are though ...

In the US there are glider kits that let old Diesel engines belch forever on highways legally.

This a very generic statement that IMHO does not point us in the right direction: NO2 concentration can be linked to a statistically lower lifespan. But it will affect vulnerable people over proportionally (so it does not decrease all of our lifespans) and it is also an effective statical proxy for other traffic pollution. (Also with rigged diesels concentration has been going down and life expectancy is increasing also for other reasons)

Unlike toxic stuff in food, regulations do not try to limit the exposure of an individual but to take action based and prioritize measures based on the statistical severity to the whole population. I do not really think that Dieselgate (while being deeply unethical many ppl kind of knew that the regulation had holes like a cheese) really made that much of a difference if you look at the situation globally. Access to clean air and water is a privilege and all rich nations and their citizens have a responsibility. It is far to easy to always just point at some rigged exhaust cleaning systems in cars. The problem is far more complex (also electric cars will produce emissions)
