Depends on what you’re cooking, but there are many types of cuisine that simply need gas burners to be properly cooked.
Unless you are doing it on open flame I have no idea how that might be possible. Heat is heat.

Evolution (and survival) only cares about if you survive to reproduce. So human evolution (and survival) matters only until 14-40, and humans aren't dying of skin cancer at exceedingly large numbers at those ages. If we pushed back the reproductive age we'd eventually evolve to live longer (though would have more people dying without reproducing first). This experiment has been successfully shown in fruit flies.
> human evolution (and survival) matters only until 14-40 I just don't think that's true. I think grand parents being around was important for human survival. If it wasn't, if all that mattered was having the most kids, then why would women go through menopause? Wouldn't it be better if women continued having children until they die? I think it makes sense that young people have kids (the sooner the better, faster ev…
Given that the risk of birth defects goes up significantly the older a woman is, menopause is probably evolutionarily advantageous.

I have a cheap pm10 meter and ran it continuously for a few weeks. Next too cooking meat the other activity that stood out was blowing out the birthday candles. The pm10 rose to 300 and only was backs to healthy levels (below 50) several hours later. I was as surprised as you are. Next time I'll definitely open a window
Where did you get a cheap meter and what do you consider cheap :D?

Just to point out how why this is a fairly nuanced topic, a shepherd may be breathing clean air but they're also exposed to UV radiation all day. They may have a higher morbidity due to increased skin cancer rates.
I'm no way an expert on the matter but by pure logic it's still amazes me how we survived (and evolved!) as a species for thousand of years without almost no shelter from direct sunlight and yet now (too much) sunlight exposure is seen as a cause of death. I know we lost almost all the body hair we used to have but still, we usually wear clothes when under the sun.

I did that too and my brakes rusted from lack of use. Ended up having to get towed for an expensive repair..
That’s a bummer to hear, and I saw other folks mentioning that on this thread too. Could you describe the climate in which you’re located? Maybe a humid, salty coastal climate will affect that differently than a dry, dusty climate.

When it comes to ultrasonic humidifiers, they do generate a lot of PM 2.5, see: https://blog.getawair.com/awair-investigates-how-your-humidi... It is NOT certain that these particles are as bad as ones from dust or combustion. All in all, when small droplets evaporate, what remains is water-soluble salts, rather than anything more reactive or harder to remove, see https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3922954/…
Are these humidifier particles bad at all? What does “cellular response” mean? Typically combustion particles are bad because they contain carcinogens and PM2.5 can deposit deep in the lungs. This seems like a “PM2.5 bad no matter the source” theory which isn’t supported at all.
It's limescale, you don't want it in you lungs. Kidney stones also have some relation to it, probably not exactly caused by hard water, but they get their building material from somewhere.

BFP is the real deal: https://en.wikipedia.org/wiki/Body_fat_percentage https://en.wikipedia.org/wiki/Body_mass_index#Limitations (however the statistics on BMI vs mortality as still completely valid)
Great now let's figure out how to measure BFP across the entire population the way we can with BMI. Every guide i've seen either uses expensive displacement equipment or trained professionals with calipers. That doesn't scale nearly as well as a height / weight calculation
I never said that. I said the opposite.
Thank you for this extensive resource on air quality. Yes, it needs to get more attention as it is one of the main drivers of mortality of environmental risks. One thing one has to bear in mind is that often when you optmize your home for low PM (e.g. with air purifiers and fixing of air leackage) your CO2 will get very high causing headaches and reduce cognitive performance. So it always makes sense for indoor air q…
I can't guess why they would be, and searching around a bit doesn't seem to suggest that's the case either.
