First time I’m interested too. I hate wearing watches and stuck to an iPhone and MacBook only until now but I’m at a high risk for heart disease. My dad died when he was only 43 from clogged arteries. I have familial high cholesterol, but statins have helped me lower to normal levels. My dad died in 1992 before statins. With statins and ecg on a watch we are all very fortunate to live in the time we do.
