Human Superhero of The Day: Scottish Woman Can Smell if Someone Has Parkinson's

Joy Milne is a real life superhero.

Les, her husband, died from Parkinson's at the age of 65. It was about 20 years after he was diagnosed with Parkinson's disease, but Joy had noticed a change in his smell about six years before his diagnosis.

That's right—Joy could smell his disease.

"His smell changed and it seemed difficult to describe. It wasn't all of a sudden. It was very subtle - a musky smell," she told BBC.

After meeting other's with the disease and noticing the same smell, Joy reached out to researchers at Edinburgh University to test her ability.

She correctly identified 12 out of 12 shirts worn by Parkinson's patients when tested.

Joy's nose-y discovery may help detect Parkinson's earlier and improve the lives of those diagnosed.
