From Tim Cook’s call on Jim Cramer’s Mad Money, as transcribed by iMore:

Cramer: Let me ask you about where you think things are going — I know that the car, the home — do you think of them as connectivity/social mobile cloud connectivity? Do you feel as though these are the next frontiers, or is there a frontier that I’m missing, I’m not thinking big enough?

Cook: Well, I think that those are two big ones that you’ve talked about. I think that Health may be the biggest one of all, because for years, people have depended on strictly someone else to determine their health. And now these devices — in essence — empower people to manage and track their own health and fitness. And so I think that market is probably significantly underestimated.

I’m confident that Apple has huge plans for personal health over the next few years. They’re just getting started now.
