PRO: The Oprah regular is a champion of yoga, a scourge of belly fat, and half of a "What's Your Real Age?" brand (with Dr. Michael Roizen), which extends over several television programs and books (such as the best seller You: on a Diet).
CON: Maybe this whole "living longer" thing is overrated. But even if it isn't, the DIY approach to health care propounded by celebrity doctors like Oz might be distracting us from tough decisions we need to make about health care collectively.
