A hostel roommate in Medellin saw my screen and said one sentence that fixed my whole work setup
I was working from a hostel in Medellin last winter and this guy from Germany glanced at my laptop and said "your screen is at chest level, how is your neck not destroyed?" I had been getting headaches every afternoon for like 3 weeks and just thought it was the altitude. He told me to stack my bag under the laptop and sit on a pillow, which sounds dumb but it raised everything up about 6 inches. Now I carry a $12 folding laptop stand everywhere and my afternoon headaches are gone. Has anyone else had a random stranger point out something so obvious about your setup?
