@Nonya_Bidniss Hope that has indeed solved it. It’s so dispiriting that in the age of so-called modern medicine we have to diagnose/solve our own issues. Surely your doc should have known if SOB can be caused by iron deficiency, and therefore should have thought to order blood tests to check your iron (and ferritin) levels. “No ideas”, smh.

@afewbugs Absolutely. And often, the unlauded/unbudgeted maintenance is critically important: when it doesn’t get properly considered in design, or carried out well, the [impressive ego] project fails! Thinking here about some high-profile buildings designed by “star” architects which develop costly leaks. Also about the huge amounts of public infrastructure, e.g. bridges, which have been poorly maintained such that they now need actual replacement at tremendous public inconvenience and expense.
