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.
When the modern notion of retirement was first articulated near the end of the nineteenth century, the designated retirement age of 65 was longer than the life expectancy at the time. Over the last 50 years, the average retirement age declined steadily; in the United States, Great Britain, and Canada, the average retirement age is currently around 62. Meanwhile, life expectancies have increased, leaving more years for leisure.
