I got a pacemaker two months ago that is airport security-friendly and even MRI-friendly. I've managed to make it through the pre-Check WTMD twice without dying. Anyone can feel the device below my left shoulder right below my skin. What in blazes is a screener from any country going to determine when they feel a lump below my skin? Do I have an atomic demolition munition the size of a Kennedy half-dollar right below my skin? How about an anthrax bomb that is suddenly going to appear from underneath my shirt? How about a cache of fentanyl?
