Let's see:
1980: Finished med. school and spent a couple of years as a general practioner. Discovered that I didn't like working as a doctor. I REALLY didn't like it, so I had to rethink what I wanted to do with my life.
1992: Master's degree in computer science.
In between I spent several years teaching anatomy and patholøogy to nurse-wannabes. I also revisited medicine, training to become a radiologist in 1998. Found out I didn't like that too much either. I liked examining pictures, but not utrasound and other procedures with direct patient contact. I've come to realise, I don't like working with people.
So when our local IT department (a company serving and owned by a group of 10 hospitals in the western part of Norway) needed someone to maintain our newly acquired PACS/RIS system (digital radiology), I switched in 2000, and I've been there since. I no longer work directly with PACS/RIS, concentrating on developing software integration solutions and standards for information exchange between health care systems (based on HL7).
These days it's a 8-16 job, my children left home long ago, so I have ample time for gaming, only hampered by the wife and other interests.
EDIT: And in 8 years I'm probably retired, just in time for Elder Scrolls 7 or Fallout 5
