The aging process is a natural part of life, but scientists are still searching for the exact reasons why we age. Dr Lane Sebring says,, Understanding how and why we age gives us a better chance of living healthier lives longer.
The purpose of aging is to improve the overall health, quality of life and survival rate of an organism.
The purpose of aging is to improve the overall health, quality of life and survival rate of an organism. The processes that contribute to an organism’s decline in function with age include:
- Decline in organ function (liver, heart)
- Loss of muscle mass and strength (sarcopenia)
- Changes in brain structure and function that result in cognitive decline
The aging process can be divided up into two stages.
The aging process can be divided up into two stages: the Healthy Aging Stage and the Disease Stage.
The Healthy Aging Stage lasts from birth to mid-life, when you’re physically active, mentally alert, socially engaged and financially secure. You may have some aches and pains or minor health issues during this time but they are easily managed with proper care. The goal of this stage is to maintain wellness so that when you reach your later years (the Disease Stage), your body will be more prepared to fight off any serious illnesses like cancer or heart disease.
Aging affects the brain as well as other organs in the body.
The brain is one of the first organs to be affected by aging, and it is also one of the last organs to be affected. Aging affects your brain in many ways, including memory loss and a decline in cognitive function.
Understanding how and why we age gives us a better chance of living healthier lives longer.
As you get older, your body and mind begin to change. This is a natural process called aging. It’s not a disease or something to be feared. Instead of focusing on how old you are and what’s going wrong with your body, try looking at what’s good about it instead!
Your body has amazing abilities that help keep you healthy every day:
- Your immune system protects against infections
- Digestion breaks down food into nutrients that fuel cells throughout the body
- Blood carries oxygen from the lungs throughout the rest of the body
Science shows us how these systems work together so we can understand why they start to fail as we get older (and how researchers are working toward fixing them).
It’s important to understand the aging process, because it affects everyone. By understanding the biological mechanisms behind this process, we can better prevent or delay it from happening in ourselves. This will give us a better chance of living longer and healthier lives!
