Oprah had Dr Oz on there. The topic was extending your lifespan. Dr Oz was discussing the huge steps that regenerative medicine has made. He swore that some of these steps could add 20 years to your life, maybe even more. Oz and Oprah then showed different means for extreme calorie burning and counting so that your cells might work more efficiently. This too, they were saying, could add decades to your life. They interviewed a 60 year old guy who said he had more energy than he did when was 20 because of his fragile and intense diet. Some people on there were practicing some of these methods Oz and Oprah were mentioning. They felt like they could live to be 120. It was fascinating.
