A job that balances that out is great. I have found that job. Not everyone does, but I did. They are out there.
I agree the balance is the best thing about it...I have far more actual time spent in my own home than ever before...18 hard days off a month is a bunch...and affords me a freedom I never had at a "real" job....however the fruits come at a price...there were days flying boxes and doctors around that were borderline misery due to the schedules.
