So just curious. Why does our bodies and organs and muscles start deteriorating at a certain point in our lives? And how come some mammals can live to be 300 years old meanwhile others are lucky to live a couple years?

Raymond Pearl based his Age of living theory upon the earlier work of Max Rubner and proposed that the maximum lifespan of an animal was related to its metabolic rate sometimes viewed as the number of heartbeats. However this may only be part of the picture with the role of reactive oxygen species in cell deterioration and eventually cell death also playing a part. https://youtu.be/ctEIbPI6A4U
