I started my career as a plumber (exterior - digging up water mains), and currently I am a corporate IT security engineer.
While the plumbing part was absolutely harder physically, the work was overall more enjoyable and much less stressful. I was outside a lot of the time, I got to play with heavy equipment, and most of the time there wasn’t much urgency to the tasks. I never stared at the ceiling at 2 am worrying what tomorrow would bring.
In corporate IT security? There are days I don’t leave my desk for 6-8 hours straight. I feel a constant need to be connected, and I’m always planning, strategizing and worrying about the next project.
Everyone talks about the sitting at the desk thing, which is an issue, but corporate life is also much more mentally taxing. And that crap adds up over 10-20 years.
