Curves of Paget's Disease

Paget's disease, aka osteitis deformans, is a "hot" disease of bone, where your bones are first degraded faster than they are built, then they recover, but in a strange and brittle way. Normally, your body is in a constant state of flux that remains relatively balanced -- unless you're vitamin D deficient (leads to rickets or osteomalacia), estrogen deficient (postmenopausal osteoporosis), etc.
