As stated in other comments, dying from old age occurs because your cells can no longer replicate and renew themselves properly, meaning your body cannot maintain a balance. Either they replicate out of control (cancer), or they stop replicating and the organs begin to fail. Also, people who’s neurocognitive abilities have been severely impaired sometimes die because their brain is simply no longer able to regulate their organs properly and things just stop working. Keep in mind that it only takes 1 organ failure to shut down the whole system.
