Yeah, it's a bit of a pain airports etc, UK is alright they understand, it's the other end with language problems is a pain. I can't be scanned with anything as my wiring is all linked up to my little delicate brain, It could possibly fry some important bits!
What's worst is, anything like that upsets the settings - as there are over a million of them, to tune it all up again takes months to get right
Luckily, I have a security pass for stuff like that and I'm always up for a full body frisk. I even got chemically swabbed in Turkey last year
