A hypertonic solution (pronounced HÄ«-per-TAWN-ik) is a solution with a higher concentration of solute (dissolved substance) than some other, specified solution (and which therefore has a higher osmotic pressure than the other solution). The solution with the lower concentration is then termed hypotonic.

Length of Retirement. If you retire at age 65 and live until 85, you'll spend 20 years in retirement. In fact, that's the average length of retirement, according to the U.S. Department of Labor. (see Resource 4) The U.S. Census Bureau counted 1.9 million people age 90 and up in 2010. (see Ref. 4) Those who retire at 65 and live to 90 or older will spend at least 25 years in retirement, typically while collecting Social Security benefits.
