Actor Brian Dietzen, known for his role as Jimmy Palmer on NCIS, recently revealed that he suffered from a stroke in 2020. He credited his Apple Watch for saving his life by allowing him to call for help when he lost control of his hands and face. Dietzen was able to regain movement shortly after the incident, as the blood clot in his brain had moved. Despite the scare, Dietzen remains active and shares his extracurricular activities on social media. NCIS season 20 is currently airing on CBS.
