For the previous 6 years I was commuting 100 miles a day, mainly motorway, it took 45 mins going in, 50 going back , I actually didn't mind it, plenty of time to 'wind down' so when I went home all thoughts of work disappeared, and going in, I had time to mentally organise what I would be doing that day.
I'm now only 7 miles from work, so I'm on the pushbike as much as I can, which in the current fuel climate is a welcome thing..
