TWO fraternal twins from Kentucky are as close as they can be – despite one being mistaken for a younger sibling due to their significant height difference. Cassidy and Caroline Carter are 23-year-old sisters from Tompkinsville, Kentucky. The pair are two peas in a pod despite Cassidy being over a foot taller than her sister. Caroline was born with McCune-Albright syndrome, a disorder that affects the bones and skin. The condition makes Caroline’s bones incredibly fragile and she has broken at least 50 throughout her life.
