Re: commute: would going for a walk or ride before and after work help? I’ve found myself biking far more during the pandemic because I can hop into a Zoom call just minutes after finishing my ride.
Yes, that's what I try to do. Unfortunately in France we are limited to a disc of 1km radius around our homes, which is a purely urban area in my case.
Good question. Since I never worked from home before, in my mind it is exactly the same thing. When the lockout ends I'll be the first to go back to the campus. Also, most of our students are yearning to resume the in-person classes. For me, doing math has always been a matter of several people scribbling together on a blackboard.
