The human body is a miraculous thing. Every organ, ranging from your heart and lungs to your liver and spleen, has its own job, functioning without any outside input. In many ways, all we have to do is take care of ourselves and not mess anything up.

But, with all of those moving parts, there’s always a chance that one issue can cause a chain reaction, affecting the rest of your body. In fact, doctors were stunned by something they found during a routine autopsy of a 99-year-old woman.

Rose Marie Bentley had seen and done a great deal during her lengthy life. All the while, however, she didn’t know that something strange was going on inside her body.
