Do you commute for 4 hours a day? Do you know anyone that does? Day in, day out, day in, day out, day in, day... you see where I'm going with this?
It drives you slowly insane. 4 hours is A LOT everyday.
That was me a few years back (Birmingham to Marlow - only 100 or so miles, but it wasn't all motorways). I could've moved south, but to south I'd get half the house for twice as much mortgage. The saving grace was it wasn't my car or my fuel. Still it's quite scary getting in a car, then arriving without being able to recall the previous 1.5/2 hours.
