But out of curiosity, how much time does the coffee nerd community spend pondering and tweaking environmental variables?

For example, ambient room temperature and relative humidity? Can't do a whole lot about pressure, short of tracking historical trends vs present air pressure and setting expectations, I suppose.

Other factors: tamping down physical, emotional irritants, such as screaming children, freshly burnt toast, headaches, etc.

And something that is adjustable but not quickly so: the (paint) colour(s) of the room. It's been something like 30 years, but ISTR hearing that different colours can affect us in subtle ways. For example, red can help stimulate the appetite. I imagine good lighting (eg, warm lighting, avoid fluorescent) is another variable.

All this to ask: do coffee nerds consider tweaking any of the above, or only those things that are in very close proximity to the grinder and espresso machine?
