My 'real world' job wasn't that bad actually... I'm an electrical mechanical engineer by trade. The area we specialized in was envelope machinery, well mainly second hand machinery.
I used to travel all over the world installing refurbished machinery and removing the surplus. These machines might sound like small desktop machines but the smallest one's we dealt with were in the range of 9 tons per unit and an average of 15 units per machine. The job was great but the down side was that I was the boss’s son... Hence I got slapped around quite a bit while I was in my apprenticeship!
I could never get back into that work again because the workload is just too physically demanding and I'm a hundred miles away from being up to it.
I got to see some fantastic countries along the way though
