flash reflection on religion and health

Another thing that interesting for me in the USA is people in everywhere try to create and live in material health. However, this doesn't keep the Americans from being religious people. Many of them believe in God and go to the churchs but actually, only small percent of these Christians are truly Christians. How the Americans can connect secular style of life with so many churhes and in general religious values I cannot understand. May be individualism help them to do this.
