Anger and stress can really fuck with your heart rate. He might be more predisposed to heart disease and is experiencing hypertension (high blood pressure) which causes blood clots. Depending on where these clots are he’ll either have a heart attack or a stroke. Since his neck starts hurting it’s probably gonna be a stroke since that happens when blood is blocked from the brain. Is it a silly plot line, yeah. But it’s not impossible, you can have a heart attack/stroke at any age depending on genetics and external factors
I don’t know why Asia was specifically mentioned, most non-European races have an increased chance of developing hypertension so maybe it’s something else unique to them. But in my limited view it’s probably hypertension followed by a stroke.
