Difficulty of a job is probably viewed differently from person to person also. I've done both programming and commercial fishing and I'd say they take different types of effort. Depending on the fishery, you could have a few months with lots of intense physical work and not much sleep, but the plus side is you get to work out on the ocean in a beautiful environment and you can travel around and not work for the rest of the year. One tech job I had, I was on call 24/7 with hours of commuting each day and it was very stressful and mentally tiring in my experience.
