8:28 AM Lath and plaster design has been traditionally used in US, Canada and British colonies since the 1700s. It has been replaced in mid 20th century by drywall and fiberboard. What did not change is the fact the walls are essentially empty, or filled with volcanic mineral insulation which breaks with the release of irritating dust and sulfur and the plaster and drywall is made with calcium sulfate which has sulfur in its formula.

Now the UK started to import the same style of building from its (former) colonies.

The air trapped between the outer panel, usually made of fiberboard and inner, currently made of mostly drywall is stagnant for decades and stale. Same goes for interior walls, with drywall on both sides. Calcium sulfate, under influence of certain bacteria slowly decomposes with release of sulfur dioxide which again breeds more weird bacteria.

During inevitable vibrations which may be due to even talking, watching TV, listening music, cars hitting bumps outside, modified exhausts etc. the "air" inside the wall loaded with weird ever mutating due to antibacterial sulfur dioxide breeds of common bacteria mixes with the breathing air inside through cracks, plugs, the half inch space between inner panels and floor, resulting in an environment that is not only unpleasant but carrying the reason for current health epidemies like cancer, diabetes, etc...

Prior to coming to the US i have only been in Germany, Italy and Moldova and never seen or heard about those. I assume in most European countries houses are currently made of bricks or concrete, oftenly prefabricated, with entire walls made in a factory and then assembled pretty quickly.

In Romania while i was a teenager cranes raising walls to be assembled into block buildings was a common sight.

I don't believe newer 3D printed houses made of concrete but still with empty spaces inside. But at least they don't have sulfur in walls.

For some reason that is (not so) hard to explain (eliminating competition, keeping the construction style) they are trying to cover this blaming in on some batches of drywall imported from China. It's not the impurities in the drywall. Drywall itself contains 23% sulfur due to its (incurable) chemical formula.

9:33 I recently started to use lost of screenshots in my posts. First it was triggered by answers like these. I had the feeling that someone goes in and manually changes the answers if i put a link to a search so i just want to freeze the first answer for people to see. Then i started to find it useful in other situations which i needed in the past but thought it was not so appealing.

Why they keep calling it AI? There is no intelligence in this answer.
