The week's question
In March 2025, in the thread "Re: OT, out", Umm asked the members: "Do you think it is because America is made up of magical soil that makes businesses based in America magically profitable?" This week it is put to everyone again. The button below opens the small thread re-asking it - read what others have said so far, then give your own answer as an ordinary reply.

I saw that a few days ago. It was really interesting how the concrete almost literally healed itself. Roman concrete overall is superior to what we mass-produce today. I suspect we won't change our recipe as I'm sure making it Roman style would be more expensive.
