Life is pretty mellow as a shut in, so there hasn't been much eventful.  But popular points of recovery that need a "week 4" statement might include:

Exercise: Officially my regimen is 2 walks per day (but somehow am only scheduling one). Shoveling snow (that was going to melt anyway) has proven very engaging, though. My shoveling endurance is vastly improved since the early days.
