Answer:
when we grow old our cells and tissue start taking less oxygen. Mitochondria are special cell part which respire and give energy. they start refusing to take oxygen and become less in number.
Other tissues like tendons, areoral,ligaments,skin etc. become loose. so, our body i said to be old.
heart muscle,brain neurons,vessels and nerves are also tissues which are most important. When they fail, our whole body become dead.
Most people doesn't know this fact. It is still under research. I hope this answer would have clear all your doubts.
