What valuable question did you answer with the data? You didn’t need a watch to know you were walking less.

> Remember, the Watch and the iPhone can do machine learning on the device.

Great, what is the machine learning?

It’s not just the amount of walking; it was also calories burned, heart rate not getting into an aerobic range, my VO2 max and other data that I’d have no idea about if I didn’t have a device monitory this during my waking hours.

Neat! You managed to not answer either of my questions:

1. What valuable question was this data answering?

2. What is the machine learning?
