What an amazing story.
I've often wondered about he ageing process. When you reach your physical peak, say for argument sake at twenty-one, why the body doesn't just maintain itself at that level. People sometimes laugh at the huge ages in The Bible, people living to eight-hundred years old etc, but I've never seen the problem. We see animals that grow older at all different rates, some that vastly outlive us, and we don't know why. If you took a snapshot of your body over a six-month period when you were twenty-one years old you would see very little change. If the body can maintain itself that way for six months why not for sixty-years instead.
I believe that people were originally designed to do just that. Maintain themselves indefinitely. What we see now is a corrupted, defective form of the original design.
