The Surprising and Fascinating Lives of Conjoined Twins

Here’s a surprising fact about the Hensel girls…because the twins do not share an immune system and vital organs, they don’t get sick simultaneously. For instance, Brittany is prone to catching colds often, and Abby never got pneumonia despite her sister contracting it. Strange, right?

Even their body temperatures are not the same! Abby feels hot more often, while Brittany feels colder—it’s quite the conundrum. Both must stay in bed and rest when one gets sick. Brittany is an introvert and is afraid of heights, while her sister is an extrovert and adventurous. Go figure out how that works!
