The nation's foreclosure crisis is now being tied to a wave of middle-aged suicides. Two researchers at Purdue University found that since 2005, the states with the highest foreclosure rates have had the most suicides. Suicides particularly spiked in the 46-to-64 age range. Researchers theorize that losing a home so close to retirement age is fueling the increase. Historically, the elderly have been the most likely to commit suicide. The paper is published in the June issue of the "American Journal of Public Health."
