In order to live a long and healthy life, you need to have a healthy body that you pay attention to. You need to eat nutritious food, get exercise and have a good lifestyle. At least that’s what conventional wisdom will tell you, but what if you have been born with a rare condition called Situs Inversus? What’s the possibility of you surviving to a ripe old age then?

Situs Inversus is a rare condition in which the major visceral organs are reversed or mirrored from their normal positions. This means that organs like the liver, stomach, and other internal abdominal organs are shifted from right to left. Rose Marie Bentley, a woman from the Pacific NorthWest never knew she even had this condition.

Her heart was still on the left side of her chest, but the rest of the organs were transposed from right to left. Her body was donated to research in 2017 after she died by her husband. It was only when the students at the Oregon Health and Science University used her cadaver for science experiments during a normal anatomy class that the rare condition was revealed. Now that’s one way to prove that your textbooks were wrong!
