A specific salt of EDTA, known as sodium calcium edetate, is used to bind metal ions in the practice of chelation therapy, e.g., for treating mercury and lead poisoning. It is used in a similar manner to remove excess iron from the body.
On average, working Americans expect to retire at age 66, four years later than the average age of retirement, according to Gallup. The expected retirement age has also gradually climbed over the years, starting at 63 in 2002 and peaking at 67 in 2012 before settling at 66 for 2013 and 2014.
Prior to 2009, the plurality of nonretired Americans planned to retire before age 65. Since then, the plurality have said they will retire after they reach age 65. These trends in Americans' expected age of retirement are from Gallup's annual Economy and Personal Finance survey, conducted April 9-12, 2015. As part of that survey, Gallup asked nonretired Americans the age at which they expect to retire, and also asked retired Americans to report the age at which they retired.
