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.
But the retirement age dropped to an average of 26.5 and median of 24.8 in 2009, and has stayed lower in the years since. It is taking another drop so far this year, with the average age down to 24.8 years and the median to 23.8 through mid-June. If those numbers hold, they would be the lowest since 1991.
