Since 1960, the average life expectancy in the U.S. has increased by nine years, and according to the Social Security Administration, individuals who are currently approaching the age of 65 can expect, on average, to live until their mid-80s (84 for men and 86.5 for women). But many individuals live well beyond the average. Between 2000 and 2014, the number of living centenarians (individuals who live to be 100 years old) increased 43.6 percent from 50,281 to 72,197. With high life expectancies and advances in healthcare and technology, people are living young lifestyles later in life. A critical component of staying and feeling young is maintaining strong mental, emotional and physical health.
