David Phelan, for The Independent:

Earlier this year, Apple’s CEO Tim Cook commented on the importance of health to the company. In a statement that has been widely quoted, he said, “I believe, if you zoom out into the future, and you look back, and you ask the question, ‘What was Apple’s greatest contribution to mankind?’, it will be about health.”
Although he only said it some months ago, it’s been a direction the company has been taking for years.

I’m meeting Jeff Williams, Apple’s Chief Operating Officer, along with Kevin Lynch, Vice President of Technology and Sumbul Desai, the company’s Vice President of Health.

The Apple Heart Study, conducted recently in conjunction with Stanford, was the largest study of its type. It examined atrial fibrillation in order to provide validation for the irregular rhythm notification, a feature available on most models of Apple Watch.
