As it turns out, that’s almost never quite what’s going on from a medical perspective. Aging – in and of itself – is not a cause of death.

When most of us say that someone died of old age, what we really mean is that someone died as a result of an illness (like pneumonia) or as a result of an event (like a heart attack) that a healthy, stronger person would likely have survived.
