What is causing people to collapse and die suddenly?

Sudden collapses and deaths can be attributed to various factors, including underlying health conditions such as Heart disease, arrhythmias, or strokes that might go unnoticed. Increased physical exertion, dehydration, or extreme environmental conditions can also contribute. In recent times, there have been concerns about the impacts of COVID-19 and its variants, as well as vaccine-related myocarditis, although evidence varies. It's essential for individuals to monitor their health and seek medical advice if experiencing unusual symptoms.
