Was reading that the queen's official cause of death was 'old age'. Which got me thinking - what is this? When someone old dies, what actually happens? I always assumed there was something which caused the death like a heart attack, cancer, malnutrition, or something. What does dying by 'old age' actually mean? Surely something in the body must have 'broken'/'stopped working'? Why isn't that something noted as the cause of death?
Age can't kill you surely. It must be the consequence of aging that kill you?
