If you want to get depressed about all the problems with trying to colonize Mars, I recommend A City on Mars: https://www.acityonmars.com/ It's by the cartoonist of Saturday Morning Breakfast Cereal and his wife (the one with an actual science PhD). https://www.smbc-comics.com/
we have similar problems with volcanic ash on earth
I walked up to the flows on Fagradalsfjall when it was erupting a couple of years ago, and I found the cinereous, sulfurous air to be very medicinal and clearing. I'm not sure it'd have good for me for more than a few hours, but as it was, it was great. I occasionally wish I were able to just have a chamber with that air in it.

Only 4 are still alive, all in their 90s so that’d be a long time - even if some do have cancer at this stage it’s not likely to affect life expectancy I guess.
We also have to remember that those astronauts were some of the most physically fit individuals in a nation of hundreds of millions which may skew the expected medical outcomes. Especially if we assume they always had the best healthcare available, if from nothing else than doctors asking similiar qiestions about the effects of space travel.
It's the same with F1. "We have the best drivers in the world!" You have the best drivers from the self-selection mechanism you impose on the sport. There are zero reasons to think these categories have good overlap.

Yeah, the ground on mars is literally toxic. Makes the concept of a Martian colony less appealing. Almost equal to a floating station on Venus. At least there you’d have the correct pressure. I seem to recall that the temperature on Venus at an altitude of one atmospheric pressure is manageable. It’s just also acidic. Possibility easier to deal with than perchlorates.
Since the perchlorate is generated by reaction with sunlight, it might be limited to a surface layer. Well, I guess that's what regolith means.
Have any of them developed cancer from the space asbestos yet?
Moon dust is still problematic since although smaller it also can't be digested by macrophages and it's believed it would accumulate in the lungs, building up on repeated exposure.

Photocopiers smell like ozone when they run if anyone’s forgotten the smell
Photocopiers smell like ozone when they run if anyone’s forgotten the smell Those are similar but sweeter. If I sterilize a room with UV it has a very distinct smell like nothing else aside from lightening and stun guns. I would UV the bathroom right now but then I have to vent the entire house and its 34F outside right now.
Diatomic oxygen is already a highly reactive fuel that is killing us and giving us cancer every single day. The ozone species is even more oxidative.
Oxygen is how we move about the energy gradient, but it's also killing us. Ozone is worse.
"Air purifiers" with ionization are probably not worth the squeeze.
I recall an article from a long time ago that basically said “astronauts report” the moon smells like spent gunpowder and outer space smell like… I think it was ozone. What they were actually reporting was the smell of the airlocks after they returned from their excursions. The moon has no atmosphere, so it has been accumulating dust from billions of years of asteroid impacts that have never come in contact with oxyg…
At least some ISS astronauts describe smelling burnt metal after returning from EVA, if memory serves. (Others may smell ozone, I've just always remembered hearing burnt metal).

I don't think any of you should want to be smelling Ozone. Diatomic oxygen is already a highly reactive fuel that is killing us and giving us cancer every single day. The ozone species is even more oxidative. Oxygen is how we move about the energy gradient, but it's also killing us. Ozone is worse.

They have a remote control that "arms" them and it starts beeping slow, the faster, then much faster then activates. It kills insects be destroying their lungs and entirely destroys mold, bacteria and even damages viral material. Hospitals run the same lamps in wings that they close down for sanitation. The entire area has to be 100% vented.

Without massive terraforming all of Mars is very hostile. But having solid ground is still nice. A workable compromise is making big habitats in a dome, that gives sunlight, but shields from radiation. And the ground needs to be processed obviously. The advantage of Venus to me is is gravity.
Venus seems like a wonderful place to live, relatively speaking. At the right altitude where you can "float" on the ocean, it's a pretty comfortable temperature and there's plenty of solar energy but you're shielded from the solar radiation. So, long term, your body will still work, assuming you can solve "the other problems." Of course, the down-side is that there's nothing to stand on and probably more importantly,…
Actually, the cloud layer at that level is mostly sulfuric acid, from which you can get your water. It also means you need to be in a hazmat suit when you walk outside, but that's still a step up from everywhere else, where you need a bulky pressure suit instead.
