It's too bad these features weren't around a couple years ago. My uncle fell to the ground and died of a massive heart attack nearly two years ago. He was an early adopter of Apple Watch and was wearing it when he died. If it was able to detect irregular heart rhythms and sudden falls back then, he may still be alive today. He was in really good shape and 53 years old. He had just returned from the gym, took a break inside because he was feeling weird, and then after a while got up and decided to go outside and wash his truck. He was like father to me because my actual father is garbage. I'm glad that Apple has developed this technology to help other people not lose loved ones like I did. I just wish it had been developed sooner.
