It's human nature to seek pleasure in life.
Having said that the majority of people eventually settle down and don't let their impulses dictate their lives.
Watching too many "reality shows" "breaking news stories" and reading trash will convince anyone that "the whole world has gone mad!" The truth is there are over 7 Billion people on the planet and the vast majority of them don't live in the United States, they are not drug addicts, alcoholics or addicted to porn. Whether someone believes in god or not they know what is healthy or unhealthy for them. The average person works 40 hours a week, pays their bills, and provides for their kids. Naturally this is not the kind of story that would make the front page of any newspaper, lead off the evening news, or generate many comments in the gossip magazines. It is very unlikely that even 1 billion people out of the 7 billion people are leading self-distructive lives. Don't believe the hype!
