While digital technology often receives brickbats from the health-conscious, a 76-year-old man in Hong Kong now wants anyone with a heart problem to wear an Apple Watch after it helped him get a new lease of life by sending an alert about his elevated heart rate.

Gaston D'Aquino, a semi-retired diamond trader, was sitting in a church in April when he spotted an alarm on his timepiece telling him that his heart rate was too high, tech website Phone Arena reported on Sunday.
