Joy's journey into understanding and harnessing her superpower was partly inspired by her husband Les, who was diagnosed with Parkinson's disease. Even before his diagnosis, Joy noticed a distinctive musky, greasy odor on him, which she initially mistook for poor hygiene. It wasn't until many years later, during a Parkinson's support meeting, that she realized her heightened sense of smell was actually detecting a hallmark of the disease. Her ability to recognize this scent led her to use her gift informally as a diagnostic tool long before scientific validation was available.
