British comedian Bob Mortimer underwent triple heart bypass surgery in 2015 due to blocked arteries. During surgery, Mortimer had a near-death experience in which he described seeing a tunnel and a light and feeling immense peace and happiness. He shared details of his NDE on a podcast, expressing how the profound event changed his perspective on death. "I no longer fear death and everything," he reported. Many who heard his story dismissed it as a metaphysical experience and instead suggested there was a physical explanation for his NDE, such as hallucinations caused by chemicals in his system.
