Work nightmare

before I went in business for myself I worked for a big construction company as a union operator. My crew was working in gas fields installing compressor sites from 6 am until 4 pm. Hunt Oil here in Tuscaloosa had an explosion so when got off work at 4pm we grabbed a bite to eat on the way and then worked from 5 pm until 1 am. Got home, showed and in bed 2-2:30 am and was back at work at 6 am about 30 miles from home. I did this for 3 weeks 7 days a week. Couldn't do it now but I was only about 48 years old then.
