Different kinds of aging factors in human body and there functions.

Yong Han*

 The function with age, our bones tend to decrease in size and density, making them weaker and more prone to fractures. Muscles typically lose strength, endurance and flexibility. These factors can affect coordination, stability and balance. Ageing and mortality of the individual organism became potential with the evolution of reproduction that occurred with the emergence of the fungal or animal kingdoms or so a billion years past, and also the evolution of seed-producing plants 320 million years past. The sexual organism may henceforward pass away a number of its genetic material to provide new people and will itself become disposable with regard to the survival of its species.
