It’s a common anecdote from med students how black the lungs are from elderly city dwellers, but that doesn’t mean people should accept it.

Is there a way to test this when people are alive rather than waiting until an autopsy.

Is there any way to remove this? I assume this is a hypothesis, should this be conclusive can it be fixed? Yes cleaner air is the better way to go, but there’d be billions of people with a clogged up immune system, perhaps unaware that would benefit from getting this removed?

Are there animals that have mechanisms to overcome this issue? I doubt many live long enough for this to be an evolutionary driver, but some may have an inadvertent mechanism.

How big a role is smoking, or passive smoking in this?

I fear these questions are proffered to a waning post.
