I would wager a lot of unnecessary Zoom meetings with far too many people on the call to be actually productive filled a lot of WFH hours along with refrigerator, TV, web surfing, and family breaks equals the deficit of commuting and walking to your desk. I use my commute to prepare for the day, not just drive or take a train, and I try and avoid Zoom while driving especially if I'm on my motorcycle! Make a F2F office meeting a Zoom meeting in person and have it record it the way you like it.
