There's a suicide in the USA every 13 minutes. A short ride from the Golden Gate Bridge where about 1,600 of these deaths have occurred over the years, actor-comedian Robin Williams took his life at his Tiburon home in August. Americans are far more likely to kill themselves than each other. Homicides have fallen by half since 1991, but the U.S. suicide rate keeps climbing. The nearly 40,000 American lives lost each year make suicide the nation's 10th-leading cause of death, and the second-leading killer for those ages 15-34.
