This is for two reasons: firstly, the long term impact of losing function in a limb is far less than people think, and the long term impact of an increased commute is far more than people think.
I have started listening to podcasts on my commute, and it's much more enjoyable than my music collection or any of the radio options here. I definitely should have started doing it earlier.
Likewise, when I decided to move 20 minutes farther away, my QOL actually improved, since I liked the area I lived in much more and there was more stuff to do after work.
After the move, it was about a 7-12 minute drive to work. Much shorter, but I liked being able to walk before and I could read or nap on the train. Had I been driving to work (instead of taking the train) before, it would have been a 1-2 hour stressful commute in heavy traffic.
As I read what I just wrote, I wonder if the reason for the "loss of limb" comparison is that the 20 minute commute they used as a reference is in heavy traffic. I have a 35-45 minute drive to work 2x a day now and again, dropping it to 15 minutes wouldn't be a big deal for me, but it is a very relaxing commute mostly along country roads where I get to drive at a consistently high speed.
Of course, if I were telecommuting I could just go take a bike ride at lunchtime on nice days, and not have to deal with darkness or bad weather or packing work clothes or rush hour traffic. Though I worry that I wouldn't.
