Assasin, from what I've seen on these boards and the professionals i've talked to (i'm not yet one myself) it seems like the family oriented guys get real tired of the job and lifestyle.

They don't have enough money to support a family. They aren't home enough to be part of a family. They aren't enjoying life.

If your single... You would have enough money to support yourself. You wouldn't have anyone complaining that you are never home. You would probably find yourself in the best job possible for a single guy who likes to travel and doesn't find being in an airplane stressful.
