Every time the patient took his medicine, the antibiotics killed the weakest bacteria in his bloodstream. Any cell that had developed a protective mutation to defend itself against the drug survived, passing on its special trait to descendants. With every round of treatment, the cells refined their defenses through the trial and error of survival. "It means that during a normal course of treatment there is an evolutionary revolution going on in your body," said Stanford University biologist Stephen Plaumbi, author of "The Evolution Explosion: How Humans Cause Rapid Evolutionary Change."
"When you talk about the evolution of an arm or an eye or a species, you might be talking about millions of years. You can get bacteria resistant in a week," Dr. Mwangi said.

To be a successful investor, one must "evolve" like the bacteria.
Charlie Munger said during BRK 2007 AGM, "I would argue that it started with a young man reading everything when he was 10 years old, becoming a learning machine. He started this long run early. Had he not been learning all this time, our record would be a mere shadow of what it is. And he’s actually improved since he passed the age at which most other people retire."
