Do you have a family?
Now that can be challenging....lol
And yes, I have had positions during my career where quick thinking, quick actions and a certain amount of bravery were required, on a 12 hour a day basis.
Some fond memories remain..
You came home after only twelve hours? Wow, I envy you. I was on the road for several years and sometimes had to fly my family to where I was just to see them. Hysteria, pure hysteria. If you were allowed to go home at night, a God sent blessing, I assure you. Motels became my home. My office was in my vehicle. I could not hide. I had a suitcase phone, a pager and a hand held radio. Not a life for a family person at all.
