what is the weirdest thing that stopped you from passing through a metal detector?

I had an LVAD for a year (Google it), and metal detectors could kill me. I had to stay away from magnets even, so conversations were weird when I had to visit a courthouse and had to bypass the security measures. I had to go through a totally different entrance after explaining that if they used the wand on me I could die & to please not kill me.

They thought I was lying at first but it’s hard to lie about a machine that is surgically attached to you lmaooo
