Alderdice, Marc: - Marc Alderdice, PhD has worked in academia and with pharmaceutical companies managing clinical trials, some for potential treatments of Alzheimer's disease. Marc has also had to deal with the disease on a personal level when his wife, Mary, was diagnosed with early-onset Alzheimer's, which was much different from studying the disease objectively. He takes us on Mary's and his emotional journey and shows us how we can "dance" more and be happier no matter what life throws our way.
