One thing I noticed after switching to WFH is that I am no longer dealing with that 15-30 minute "mental haze" that happens right after I finish my 2 hour car commute: That decompression period where my brain is fatigued from being on high alert, white knuckling it down I-580, then I-680, then I-880, watching for hazards, accidents, or just slogging through bumper-to-bumper traffic. I'd walk into the office but my brain was just too fatigued to work without a little time spent just walking around like a normal person.
