In the first episode, Walt is told by his HMO-approved doctor that his “inoperable” cancer gives him “a couple of years” to live. Walt rejects this downer diagnosis and chooses an out-of-network cancer-killing regimen that he pays for with his meth wages. Now, how long would Walt have lived if he’d survived long enough to die of cancer, rather than from the dragon that swooped down and killed him in the final scene (man, that was one unexpected twist ending)? Judging by his awful health in the last episodes, the answer is: about two years. In other words, Walt’s out-of-network treatment with the “oncology dream team” doesn’t actually achieve anything, except maybe provide an excuse to wear an awesome hat.
