I had a disc in my neck replaced with a titanium plate a few years ago and I always get teased that if I get hit the wrong way that my head will fall off. Never had a problem going through airport security - I don't think titanium rings as many bells as other metal replacement parts.
I always thought it would be fun if you could go into a store like Pep Boys and just pick up body replacement parts - I can see this way off in the distant future!
Everyone have fun on all your trips to distant lands!
