I have a titanium WHAT in my head?

I went in for another doctor's appointment yesterday and discovered that I have a titanium plate (plus a few screws) holding my skull together as it heals. This is something they neglected to tell me after the surgery, so it came as a surprise. I'm not sure why, as it makes sense that SOMETHING would need to do that job, but it did.

I have no idea if this is something they would remove after a set amount of time, but as they haven't discussed that possibility with me I seriously doubt it. I also don't think this will set off alarms at airport security...but you never know. I have to admit, it would be really entertaining to have them wave the wand all over me and discover that the alarm is coming from my head. I've already had an MRI with no problems (it would be a poor neurosurgeon who puts a metal in your head that wouldn't work with his diagnostic tools) and I can't think of any other scenarios where this would be a problem...

Inevitably, after sharing this news with my family, it became a source of amusment.

"Does this mean that you could actually have a 'screw loose' at some point?"
"You know...submarines are made out of titanium. Do you think you're an attack boat or a boomer?"
"What about a periscope attachment?"

Ah, family. Feel the love.
