One thing I love about Apple is that they are building products for what their leadership team actually needs/wants and uses themselves. This started with iPhone (e.g. what kind of smartphone do we want instead of all that blackberries?) and is very obvious with Apple Watch line.
This is great and one of the reasons why their products offer genuinely best user experience.
It does explain why the Apple Watch tracks of lot of metrics mostly applicable to the elderly - Double Support Time, Walking Asymmetry, Walking Steadiness.
