I didn't read these comments but I usually read them for entertainment value...sometimes they are hilarious and definitely better than the article or the writers point.

I had a pair of titanium glasses(spectacles) once. They were light weight and you could take the piece that runs back to your ear(forgot what the call that) and twist it into a loop...let go and it would spring right back to the original position. Pretty entertaining stuff. I guess that's one of titanium's selling points...flexibility.
