Update: The New York Times reports on a source claiming that Jobs has been suffering from "ups and downs" typical of those dealing with immune system issues related to liver transplants, but that Jobs had recently scaled back his activities at Apple as one of those down cycles began in recent weeks.

Mr. Jobs suffers from immune system issues common with people who have received liver transplants and, as a result, his health suffers from frequent "ups and downs," according to a person with knowledge of the situation, who agreed to speak on condition of anonymity because he was not authorized to discuss it.

In recent weeks, Mr. Jobs began a down cycle and slowed his activities at Apple, the person said. Mr. Jobs has been coming to the office about two days a week, and appeared increasingly emaciated, the person said. He frequently lunched in his office, rather than in the company cafeteria, the person said.
