I love my commute. It's about half an hour, in the car, audiobook on. It's a real switch between home and work.
nothing stops you from going for a run or something to make the switch, that's the point.
As soon as the restrictions are gone, your options will be unlimited. If you HAD to find that half an hour to commute, you can find it even if you don't have to commute.
I don't advocate WHF for the sake of being stuck in a tiny room and have no life, I love it for being able to compartmentalise work, close the door and have a life.
The alternative is commute, be stuck in an office for hours, not that efficiently due to the people who waste your time and energy there, commute back, deal with house chores, catch up with more work in the evening.
Even going to the gym or for a run whilst in the office, having to take a shower and get change at lunch time is really not that practical.
Being able to have time for family and hobbies instead, to see friends is making a massive difference to quality of life and mental health. Instead of being stuck in the office on Friday, I can go away for the weekend and finish work in my weekend rental, and only come back on Monday morning!
You just need restrictions to ease. I never want to work full time in an office again - I will have to meet clients and team from time to time, but as little as possible.
