Women get implants for a number of reasons, but the thought that they might one day save their life is probably not one of them.  Yet that's exactly what happened to one Beverly Hills grandmother when a coworker's husband ran into their office one afternoon and shot her in the chest. 

Lydia Carranza had implants put in a few years ago to take her from a B cup to a D cup.  Jaime Paredes burst into the dental office where she worked and killed his wife before turning on her. 

The surgeon who operated on her told the LA Times: "She's just one lucky woman.  The bullet fragments were millimetres from her heart and her vital organs. Had she not had the implant, she might not be alive today."

Can you believe that?  Talk about a good investment!  Does this mean Heidi Montag is basically invincible now?
