More than 50,000 missionaries are currently serving full-time missions for The Church of Jesus Christ of Latter-day Saints, otherwise known as the Mormon Church. Their two-year missions have taken them around the globe to third-world countries to help the poor, feed the hungry, teach English, build schools and homes and teach people about Mormonism. Most are young men and women under the age of 25, serving in nearly 350 missions throughout the world. Missionaries pay their own expenses for their service, and after two years of work, return to their home countries and their ordinary lives. During their mission, they are required to dedicate all of their time to missionary work and are not allowed to read newspapers, listen to popular music, surf the Internet or watch TV or movies. They can only call home twice a year on Christmas and Mother's Day. Along with the restrictions the missionaries face, all Mormons are forbidden to drink alcohol, coffee or tea, smoke cigarettes or have premarital sex.
