It’s waking time, not sleeping time, which is out of a 16 hour waking day.

5 hours a week makes about 20 hours a month roughly, which is about half an extra work week to live that you miss out on.

Multiply that 30 minute commute each way by 12 months and it’s close to 260 hours a year.

160 hours a month of work so you get back about 1.6 working months to put into something else.

I had a few minute commute for 10 years. It was an unfair advantage.

I too prefer a voluntary 20 minute walk over a mandatory one. Then my brain can be aimed at what I value, not work.
