<h3>What is aging?</h3>
Aging is a natural process that occurs in living organisms when they become older or as time passes.
During aging, certain physical changes that usually result in reduced abilities of normal body functions occur which are the observable features of aging. They include:
- Loss of bone mass
- decreased muscle mass
- thinning of the heart
- stiffening of the arteries
- decreased lung capacity, etc.
Therefore, some of the physical changes associated with the aging process are: 
- Loss of bone mass
- decreased muscle mass
- thinning of the heart
- stiffening of the arteries
- decreased lung capacity, etc.
