Good to see a thread intelligently and well argued from both sides. I was interested in this topic because I've thought of moving onto frieght in the past. My domestic situation dictates I stay here (on TPs) and I don't have a problem with that. The older you get, the more important quality of life becomes.
However, stick your LHS/RHS rubbish up your jumper, the REAL action is in proper aircraft in the seat just behind the F/O (if you can find one outside of a museum, where mines is).
