But home demands are a crucial bit of the equation. I'm nearly 50 and have a 7 year old daughter. If my commute ran much longer than an hour each way, I'd be stealing time from my family and I don't want to do that. (In fact, I quit a perfectly good job because I had to DRIVE an hour each way).

If I was 20 and single again, a 2 hour commute might seem very reasonable. In that case it's more a matter of: what do you want to spend your time on?
