If you had a metal plate in your head, would you worry about it rusting?

Yes and i would worry if there were no metal carrots, potatoes and yorkshire puddings on it of a Sunday.

No. Rust is caused by oxidation. As long as the metal in within your body, free oxygen does not get a chance to react with it to cause rust. Additionally, most metal rods and plates used surgically are either non-ferous, or stainless steel, so even if exposed to oxygen, they would not rust.

I'd worry going through a metal detector at an airport

Nope

Yeah but not near as worried as I would be of lighting

No, but I'd be worried during a thunder & lightning storm, haha.
