I recently underwent some medical tests — just routine lab work, really — and for the first time in a long time, the results did not fill me with a creeping sense of my own mortality. Numbers that needed to be going down were heading in that direction. Vitals that tended to produce descriptions like "concerning" or "alarming" were decidedly less so. I'm not a picture of perfect health by any means, but I'm certainly inching closer in that direction.
And I have the iPhone to thank for a lot of that.
