A promissing paragraph for the success of Afrezza:

"A range of physiological stresses, including obesity, pregnancy and aging, all tend to increase demand on beta cells to produce more insulin, Dr. Accili said. It may be that they are “taking a little rest,” he said, in returning to a less active state. Although it’s not yet clear why this might happen, the finding may lend support to the view that doctors should focus on relieving stress on the beta cells rather than pushing them to produce more insulin, which may speed the progression of diabetes, Dr. Accili said."
