Q: People have a genetic coding that basically extends life to approx 125 years old.  Our genetic make up accounts for approximately 30% of our life expectancy.  Environment and habits accounts for the other 70%.  Our bodies are constantly breaking down and our body does not have the ability to repair these breakdown indefinately.  Once our body loses the ability to repair our breakdowns we begin to see signs of aging.  Once the process begins we are unable to effectively stop it.  Maybe with advances of science and gene therapy we can extend our ability to repair but until then you are kind of stuck with your genetic make up.
