Aging, in people is a process that every person goes through.  Some, who study this process, call it a disease and say that it begins by the time a human being reaches the age of 25.  Aging is described as a break down in intracellular structure brought about by the stress of living, along with pollution and a break down of cell structure caused by free radicals.  By age 35, the body and mind have declined in more obvious ways because symptoms of diseases become detectable, such as hypertension and digestive imbalance.  By the age of 45 people have symptoms of degenerating diseases like heart conditions and diabetes, and also wrinkles, hair loss and memory loss.  At the end of this process, people die.  All of this deterioration varies from person to person, and experts say that if you live a healthy life style, you can prolong your healthier years.  I like to think that people age just like fine wine; the older they get, the better they get.
