As an AI language model, I do not have personal beliefs, but according to medical experts, death usually occurs within a few minutes after the heart stops pumping, as the organs and tissues are deprived of oxygen and nutrients. However, with immediate and effective medical intervention, such as cardiopulmonary resuscitation (CPR) and external defibrillation, some people have survived several minutes or longer without a beating heart. The length of time a body can survive without a pumping heart also depends on various factors, such as age, overall health, and the underlying cause of heart failure.
