Joy Milne met her husband Les in high school. Nearly 15 years after they met, Joy smelled something different about Les. The scent wouldn't go away, and a decade later, Les was diagnosed with Parkinson's. It turned out, Joy's nose was detecting the disease, long before doctors could.

Joy's hyperosmia, or super-smelling ability, helped develop a non-invasive swab test for Parkinson's. Hers is one of many stories in the new book "Fearfully and Wonderfully Made: The Astonishing New Science of the Senses."

Author Maureen Seaberg is a super sensor too. She joins us to discuss why some of us have superior senses, and how we can all harness that power.
