I was a digital nomad from late 2006 for two years, I was changing cities, countries, continents with a GT3-BH ATX case and a 15" monitor in my carry on. It was exciting. These days I live a very sedentary life style primarily in Vancouver, Canada; secondarily in Balatonalmádi, Hungary and sometimes as much as five months pass between two flights. But, sometimes I still do seven days-seven airbnbs-in-five-countries trips. I also have too many backpacks due to my obsesssion of trying to fly with a >20" monitor. Gave up. 19.5" is enough.
I never consent to full body screening. You shouldn't either. It would immediately collapse the security theater if everyone opted out.
