Dude... It's totally, completely, fully different. Have you ever worked as an electrician/plumber, etc.? The amount of physical stress, sweat, exposure to bad weather, etc. are orders of magnitude higher than what you get as a tech worker, even in 38°C heat even without an AC. Your comment reads like it's coming from someone who never ever worked physically even as a volunteer/for fun. Any non-trivial amount of physical work will tell you that it’s many orders of magnitude tougher than working with computers. The worst part is you gotta show up and work your ass off even when you have flu, or something like that, or you lose a day's wages.
