Software is "nice" because I can flex muscles and achieve things independent of "work." Many endevours require groups of humans to do; it is tablestakes.
Writing is the same, and hence why I like it so much.
It's the opposite, it's all those little details and an overview of what goes into writing a proper book (and other things). It is a collection of all that which you may not know when first starting out. It is not everything, but it is a good starting point
I wouldn't overthink it. Opening windows frequently is a good thing. Doing it during winter is even better. Oh and use crbon/hepa air filtering in bedrooms while sleeping.
But a roof is the "main cost event" to maintain a single family home in a decade timescale. With decades/century timescales and the flux increase appreciating nature of housing, these type of costs are pulverized to the ground. $27/month really became at least half that on inflation alone (seeing the past thirty year on the dollar), coupled by increases equity of the house, renos done on borrow, and over its course of time it becomes cents or disappears into an upside.
I think it will be more interesting with "basic structure integrity" at the century scales. Do we really know economic impacts when tract housing/wood structures are tested well? I'm thinking past time scale of the electric and plumbing overhauls at the 50-100 year marks. There is a ton of housing out there that is less than a century old.
