I always say that programmers have it as hard as miners, but it's a different kind of challenge. One is more physical, another mental (not going insane from sitting in front of computer all the time).
You have the comparison, What do you think?
Even in the positions that were physically demanding your body "adjusts" to the workload and it becomes rather similar to sitting in front of a computer basically you go into periods of "auto-pilot" and then other times it was somewhat mentally demanding.
Most mining operations are heavily automated requiring at least some knowledge of I.ndustrial C.ontrol S.systems ICS/SCADA is somewhat of a programming work flow. If this valve is open turn on this other valve once this sensor is tripped turn off this motor and close this valve. From a very simplistic manner this is similar to binary logic.
At least from what I have experienced infosec is very mentally challenging, but it is not a constant demand there are definitely periods where I am in auto-pilot. The best solution for me having gone to a sedentary work life is to walk to work, drink lots of water at work (make you get up to pee alot) and to take walks at lunch.
