There are many reasons why a person might look younger than his or her friends and while taking care of one's self is very often the key to feeling and looking young beyond one's youthful years, beyond maintaining a healthy lifestyle and using natural beauty products, it's very often genetics that allow a person to remain youthful far into middle age. One of the best places to look for whether a person will age well is a person's biological parents as their appearance can very often dictate how well or how poorly a person might age in later years.
