a bit off topic, but i can logically guarantee you that smoking takes at least 5 minutes off your life. It takes that long to smoke a cigarette... You have to put things into perspective, why should you care less about living now then in 40 years in the future? Chances are your quality of life will only get worse etc.

Not if smokers multitask, like making your contact cleaner solution in the factory or making your delivery food. IMO, all cigarettes should have cyanide added to them to reduce the costs to society by speeding-up the slow suicide and excess harm to others.

should all diesel cars have lead fumes pumped into the cockpit? Should all alcoholic drinks contain methanol?

> anyone who works in the subway should be dying, what, 10 years earlier? From my ad-hoc survey of subway driver friends, this seems about true... Most die in their late 60's in a country where most people make it to 70/80. Obviously the fact their job involves sitting in a chair all day doesn't help things...

Is there a fundamental reason why the subway must be like that? I assume it's not as bad in say Hong Kong? Copenhagen metro for example is automated and there's a wall and automatic doors separating the tracks from the platform. I assume it's quite clean.

I was surprised about the actual driving too. Vancouver's Skytrain is automated and largely outdoors, with the exception of occasionally needing to take a train over manually

Get a TDS meter and measure PPM in your water. Reverse osmosis filtered water will do, just activated carbon filtered water will not.

You can't readily buy DI water, but you can buy distilled water. The two are entirely different purity levels.

nox is a combustion byproduct so probably that?

Yeah I would assume it was coming mostly from nearby cars.

The crazy thing is there are no nearby cars. There is a highway about 1.5km away which I assume it must all blow from. There is nothing else within 1.5km

EVs reduce tailpipe exhaust near roads but it's worth noting that brake abrasion dust isn't going away anytime soon and it's considered very bad to breathe, possibly in the same league as diesel emission particles.[1] I guess regenerative braking on an EV reduces this somewhat. Tire dust is also concerning.[2] [1] https://academic.oup.com/metallomics/article/12/3/371/595624... [2] https://pubmed.ncbi.nlm.nih.gov/2264…

Most EVs indeed use regenerative braking. Which means your brake pads last a lot longer as you barely use them. Tire particles are a bigger problem. Just think of the mass of tires that you erode away before you replace them (routinely) and compare that to the brake pads you replace much less often. And it's not just the tires that erode but also the road. Asphalt particles are nasty as well. Though most of that dust…

EVs might as well be replaced with rail cars. In which case, it would be better to have local and national trams rather than single-occupant vehicles.

It also would be cheaper to have carbon-captured concrete bicycle and walking paths rather than asphalt highways or roads.

Single-occupancy vehicles need to go away.

Micro-managing your life to this extent is probably why all dystopian books/movies involve some well-meaning technical person who thinks we should be doing XYZ to prolong our lives.

While these things may (anecdotally) prolong your life, does anybody really want to be 102 and having to be nursed for all the basic needs like bathing yourself?

Combine this article with the many(many) others that tell you how to micro-manage all aspects of your life(to be "super productive") and you instantly find that once you start to deviate from your steady-state of micro-management, your worry skyrockets.

Reverse osmosis filtered water is mainly what I have in mind, companies sell that. 6-14 PPM is what I measured personally and I think it falls into this category.

I lived in BKK for over a year and I checked the AQI like weather. I bought a reliable pm2 reader. Air filtering system for my house and wore a mask religiously outside. The air was so bad that I began to get very ill before i started to employ these 'Micro-managements'

I never understood perspectives akin to "why would I want to add years to my life when I'll just be old anyways?". I think many people don't realize that if you take care of your body (especially eating well and movement) you not only extend your lifespan but your quality of life as well in the later years.

Anecdotally, my parents exercise regularly and take decent care of themselves compared to their friends (I even got them juicing regularly). You can tell the difference because most of their friends of the same age are dying or living a severely reduced quality of life while my dad still plays hockey regularly and my mom exercises daily. Both have very few health issues (other than a bit of high blood pressure).

I guess what I'm getting at is that it's kind of sad to me that we've become so used to the idea that old age automatically = shitty when I think there is so much that we could be doing that would mean we could live long lives AND still have autonomy and comfort. I definitely agree that if you micromanage things to a level where you are just stressing or orthorexic that's not good, but I don't think that's the only approach if you want to live a long, healthy life.
