Pagets Disease of BoneNever heard of it? I'm not surprised. It doesn't usually affect anyone under 50 after all. As you may deduce, it's a bone disease. It's most prevalent in those of UK and European descent (including those who settled elsewhere like USA or Australia) with those from Scandinavia or Asia being significantly less likely to be affected.Fun Fact: Pagets disease of bone is one of a couple of conditions, all named after the same person: Sir James Paget (rhymes with gadget), a super smart surgeon and pathologist who was a dear friend of Charles Darwin.
